The THI5 gene family of Saccharomyces cerevisiae: distribution of homologues among the hemiascomycetes and functional redundancy in the aerobic biosynthesis of thiamin from pyridoxine.

Abstract excerpt

The THI5 gene family of Saccharomyces cerevisiae comprises four highly conserved members named THI5 (YFL058w), THI11 (YJR156c), THI12 (YNL332w) and THI13 (YDL244w). Each gene copy is located within the subtelomeric region of a different chromosome and all are homologues of the Schizosaccharomyces pombe nmt1 gene which is thought to function in the biosynthesis of hydroxymethylpyrimidine (HMP), a precursor of...
