title: Cloning and sequence of the LYS2 homologue gene from the osmotolerant yeast Pichia sorbitophila.
abstract: We have isolated the Pichia sorbitophila LYS2 (PsLYS2) gene by complementation of a lys2 Saccharomyces cerevisiae mutant. The sequenced DNA fragment contains a putative ORF of 4197 bp and the deduced translation product shares a global identity of 66% and 58% to the Lys2 protein homologues of Candida albicans and S. cerevisiae, respectively. Analysis of PsLYS2 sequence suggests that, similarly to S. cerevisiae LYS2, it codes for a polypeptide having two separate enzymatic activities which reside in different domains of the protein, including an adenylate domain, an acyl-carrier site and a short-chain reductase domain. Several GCN4- and NIT2-binding motifs have been matched in the promotor sequence of PsLYS2. In addition, upstream of the sequenced PsLYS2 sequence, we have found the 3'-terminal half of a gene of same orientation encoding a RAD16-like protein, a genomic organization similar to that of C. albicans.
