Abstract:
With reverse transcriptase PCR, the transcripton of copper homeostasis relative gene Afe0329 in Acidithiobacillus ferrooxians standard strain ATCC23270 was investigated. The further analysis of genes in this transcripton was analyzed employed by Vector NTI, Blast, TMHMM Server, PSORTb software and so on. From the DNA of different strains, the transcripton of Afe0329 was amplified using special primer pairs to identify the universality of it in the genome of A.ferrooxidans strains. The results showed that gene Afe0330 and Afe0331 were cotranscribed with Afe0329, and they were in a single transcripton. Gene Afe0329 was supported to express a P1b3-type ATPase which is a heavy metal ion pumping transmembrane protein, protein AFE0330 which expressed by gene Afe0330 was a cytoplasmic protein, no significant ho- mologous sequences of Afe0330 or Afe0331 had been obtained by Blast analysis. And the transcripton of Afe0329 was universal in genome of A. ferrooxidans strains.
