A secY homologous gene in the crenarchaeon Sulfolobus acidocaldarius

Abstract

The nucleotide sequence of an open reading frame, located upstream of the gene for adenylate kinase, was determined in the thermoacidophile crenarchaeon Sulfolobus acidocaldarius. Data bank searches identified the sequence as a secY homologous gene. The DNA derived protein sequence of total 463 amino acids contains 10 hydrophobic domains. A sequence alignment with other prokaryotic and eukaryotic secY sequences reveals significant homology, but the secY primary sequence of S. acidocaldarius shows only a low degree of similarity with the secY counterparts of the euryarchaea Methanococcus vannielii and Haloarcula marismortui. A transcription analysis indicates, that the secY gene is cotranscribed with the gene coding for adenylate kinase.
