The nucleotide sequence of the glucoamylase gene GLA1 from Saccharomycopsis fibuligera KZ.
The nucleotide sequence of the 2544-bp PstI fragment carrying the glucoamylase gene of Saccharomycopsis fibuligera KZ, designated as GLA1, has been determined. When compared with the nucleotide sequence of the GLU1 gene one nucleotide substitution was found in the 321- bp of the 5'-flanking region: 24 nucleotides were altered within the 1557 bp of the structural gene causing the deduced protein products of both genes to differ in three amino acids in the signal-peptide region and in eight amino acids of the mature protein. Six nucleotide insertions and 27 substitutions were in the 663 bp of the 3'-flanking region. The gene product expressed and secreted in Saccharomyces cerevisiae into the functional enzyme was not homogeneous. In situ detection of the enzyme in a polyacrylamide gel revealed two dominant and three minor bands.
