[Identification and cloning of partial mbh2 gene cluster of hyperthermophile Aquifex pyrophilus].
A 0.8 kb fragment of mbhS2 gene of Aquifex pyrophilus was obtained by PCR with designed primers basing mbhS2 gene of A. aeolicus. It showed 85% homology with the corresponding region of A. aeolicus. Using it as probe, a 5.0 kb Nco I fragment was fished out from the partial genomic library of A. pyrophilus. Then this fragment was cloned, subcloned and sequenced. The result revealed that the fragment contains the full length gene for the mbhS2, the gene orf1 and the first 366 bp of orf2. Comparison with mbhS2 and orf963 of A. aeolicus shows 81% and 60% homologies in amino acid sequence, respectively.
