Progress in Biochemistry and Biophysics 2024;51(5):985-999
Endo-beta-N-acetylglucosaminidase (ENGase) is widely distributed in various organisms. The first reported ENGase activity was detected in Diplococcus pneumoniae in 1971. The protein (Endo D) was purified and its peptide sequence was determined in 1974. Three ENGases (Endo F1-F3) were discovered in Flavobacterium meningosepticum from 1982 to 1993. After that, the activity was detected from different species of bacteria, yeast, fungal, plant, mice, human, etc. Multiple ENGases were detected in some species, such as Arabidopsis thaliana and Trichoderma atroviride. The first preliminary crystallographic analysis of ENGase was conducted in 1994. But to date, only a few ENGases structures have been obtained, and the structure of human ENGase is still missing. The currently identified ENGases were distributed in the GH18 or GH85 families in Carbohydrate-Active enZyme (CAZy) database. GH18 ENGase only has hydrolytic activity, but GH85 ENGase has both hydrolytic and transglycosylation activity. Although ENGases of the two families have similar (β/α)8-TIM barrel structures, the active sites are slightly different. ENGase is an effective tool for glycan detection andglycan editing. Biochemically, ENGase can specifically hydrolyze β‑1,4 glycosidic bond between the twoN-acetylglucosamines (GlcNAc) on core pentasaccharide presented on glycopeptides and/or glycoproteins. Different ENGases may have different substrate specificity. The hydrolysis products are oligosaccharide chains and a GlcNAc or glycopeptides or glycoproteins with a GlcNAc. Conditionally, it can use the two products to produce a new glycopeptides or glycoprotein. Although ENGase is a common presentation in cell, its biological function remains unclear. Accumulated evidences demonstrated that ENGase is a none essential gene for living and a key regulator for differentiation. No ENGase gene was detected in the genomes of Saccharomyces cerevisiae and three other yeast species. Its expression was extremely low in lung. As glycoproteins are not produced by prokaryotic cells, a role for nutrition and/or microbial-host interaction was predicted for bacterium produced enzymes. In the embryonic lethality phenotype of the Ngly1-deficient mice can be partially rescued by Engase knockout, suggesting down regulation of Engase might be a solution for stress induced adaptation. Potential impacts of ENGase regulation on health and disease were presented. Rabeprazole, a drug used for stomach pain as a proton inhibitor, was identified as an inhibitor for ENGase. ENGases have been applied in vitro to produce antibodies with a designated glycan. The two step reactions were achieved by a pair of ENGase dominated for hydrolysis of substrate glycoprotein and synthesis of new glycoprotein with a free glycan of designed structure, respectively. In addition, ENGase was also been used in cell surface glycan editing. New application scenarios and new detection methods for glycobiological engineering are quickly opened up by the two functions of ENGase, especially in antibody remodeling and antibody drug conjugates. The discovery, distribution, structure property, enzymatic characteristics and recent researches in topical model organisms of ENGase were reviewed in this paper. Possible biological functions and mechanisms of ENGase, including differentiation, digestion of glycoproteins for nutrition and stress responding were hypothesised. In addition, the role of ENGase in glycan editing and synthetic biology was discussed. We hope this paper may provide insights for ENGase research and lay a solid foundation for applied and translational glycomics.

Spinal intradural (subdural and subarachnoid) hematoma following percutaneous kyphoplasty is an extremely rare complication. In this report, we described a case of 2 episodes of subarachnoid hemorrhage with delayed paralysis after kyphoplasty. A 73-year-old man underwent percutaneous kyphoplasty in our hospital an osteoporotic vertebral fracture at the T12 level. On the 55 h after kyphoplasty for T12 osteoporotic vertebral fracture, he developed paralysis of the lower limbs. An emergency posterior decompression from T8 to L2 was performed. And the subarachnoid hematomas were removed. Postoperatively, the neurological symptoms improved rapidly. However, 2 weeks after the operation, the patient experienced a setback with severe neurological decline (paraplegia with sensory and autonomic dysfunction). An emergency posterior decompression from T5 to L2 was performed. The subarachnoid hematomas were removed. This case reflects the cause and progression of spinal subdural hematoma. Previous literature has debated the best treatment approach for spinal subarachnoid hemorrhage, but the prognosis of patients is heavily dependent on precise symptom evaluation and localization.

ObjectiveBased on ultra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MSE) technique, we identified qualitatively the metabolites of aristolochic acid(AAs) in rat in order to analyze the metabolic differences between water extract of Aristolochiae fructus(AFE) and Aristolochic acid Ⅰ(AAⅠ). MethodSD rats were selected and administered AFE(110 g·kg-1·d-1) or AAⅠ(5 mg·kg-1·d-1) by oral for 5 days, respectively. Serum, urine and feces were collected after administration. Through sample pretreatment, ACQUITY UPLC BEH C18 column(2.1 mm×100 mm, 1.7 μm) was used with the mobile phase of 0.01% formic acid methanol(A)-0.01% formic acid water(B, containing 5 mmol·L-1 ammonium acetate) for gradient elution(0-1 min, 10%B; 1-7 min, 10%-75%B; 7-7.2 min, 75%-95%B; 7.2-10.2 min, 95%B; 10.2-10.3 min, 95%-10%B; 10.3-12 min, 10%B) at a flow rate of 0.3 mL·min-1. Positive ion mode of electrospray ionization(ESI+) was performed in the scanning range of m/z 100-1 200. In combination with UNIFI 1.9.4.053 system, the Pathway-MSE was used to qualitatively analyze and identify the AAs prototype and related metabolites in biological samples(serum, urine and feces), and to compare the similarities and differences of metabolites in rats in the subacute toxicity test between AFE group and AAⅠ group. ResultCompared with AAⅠ group, 6, 10, 13 common metabolites and 14, 20, 30 unique metabolites were identified in biological samples(serum, urine and feces) of AFE group, respectively. Moreover, the main AAs components always followed the metabolic processes of demethylation, nitrate reduction and conjugation. Compared with common metabolites in AAⅠ group, prototype components of AAⅠ in serum and most metabolic derivatives of AAⅠ[AAⅠa, aristolochic lactam Ⅰ(ALⅠ)a, 7-OHALⅠ and its conjugated derivatives] in biological samples were significantly increased in AFE group(P<0.05, P<0.01), except that the metabolic amount of ALⅠ in feces of AFE group was remarkably lowed than that of AAⅠ group(P<0.01). In addition, a variety of special ALⅠ efflux derivatives were also identified in the urine and feces of the AFE group. ConclusionAlthough major AAs components in AFE all show similar metabolic rules as AAⅠ components in vivo, the coexistence of multiple AAs components in Aristolochiae Fructus may affect the metabolism of AAⅠ, and achieve the attenuating effect by increasing the metabolic effection of AAⅠ and ALⅠ.
