title: Cloning and molecular analysis of two different ILV5 genes from a brewing strain of Saccharomyces cerevisiae.
abstract: Two different ILV5 genes encoding acetohydroxy-acid isomeroreductases, and named ILV5G and ILV5X, were cloned and sequenced from a Saccharomyces cerevisiae brewing strain. The coding sequence of ILV5X shows a single nucleotide change with respect to that from the ILV5 gene of a S. cerevisiae laboratory strain. In addition, all promoter motifs which are, or are presumed to be, implicated in transcription regulatory functions are identical in ILV5 and ILV5X. In contrast, the coding sequence of ILV5G differs in 5.6% of its nucleotides from that of ILV5 and most of its promoter regulatory motifs show a single nucleotide change with respect to those from ILV5.
