Seiboth B, et al. (2002) The Hypocrea jecorina gal10 (uridine 5'-diphosphate-glucose 4-epimerase-encoding) gene differs from yeast homologues in structure, genomic organization and expression. Gene 295(1):143-9
Abstract: As part of a comprehensive study on lactose metabolism in Hypocrea jecorina (anamorph: Trichoderma reesei), a genomic clone of the gal10 gene encoding H. jecorina uridine 5'-diphosphate (UDP)-glucose 4-epimerase has been cloned and sequenced. It contains an open reading frame of 1548-base pair, interrupted by three introns, and encoding a 370-amino acids protein with similarity to pro- and eukaryotic UDP-glucose-4-epimerases. H. jecorina Gal10 does not contain the C-terminal mutarotase domain which is present in yeast Gal10 proteins but is able to functionally complement a corresponding Saccharomyces cerevisiae gal10 mutant. gal10 is not clustered with other H. jecorina gal genes (gal7, gene encoding galactose-1-phosphate uridylyltransferase and gal1, gene encoding galactokinase). The genomic location of H. jecorina gal10 and gal7 was syntenic with that in Neurospora crassa and colinear over an area of 6 and 3.5-kilobase. gal10 is constitutively expressed, and - unlike H. jecorina gal7 - not further stimulated by D-galactose or L-arabinose or its corresponding polyols.
