A Cryptococcus flavus gene (AMY1) encoding an extracellular α-amylase has been cloned. The nucleotide sequence of the cDNA revealed an ORF of 1896 bp encoding for a 631 amino acid polypeptide with high sequence identity with a homologous protein isolated from Cryptococcus sp. S-2. The presence of four conserved signature regions, (I) 144DVVVNH149, (II) 235GLRIDSLQQ243, (III) 263GEVFN267, (IV) 327FLENQD332, placed the enzyme in the GH13 α-amylase family. Furthermore, sequence comparison suggests that the C. flavusα-amylase has a C-terminal starch-binding domain characteristic of the CBM20 family. AMY1 was successfully expressed in Saccharomyces cerevisiae. The time course of amylase secretion in S. cerevisiae resulted in a maximal extracellular amylolytic activity (3.93 U mL−1) at 60 h of incubation. The recombinant protein had an apparent molecular mass similar to the native enzyme (c. 67 kDa), part of which was due to N-glycosylation.
