RESUMO

A gene encoding Rhizopus niveus aspartic proteinase was isolated from an R. niveus genomic library by using oligonucleotides probes corresponding to its partial amino acid sequence, and its nucleotide sequence was determined. By comparing its deduced amino acid sequence with the amino acid sequence of rhizopuspepsin (5, 26), we concluded that the R. niveus aspartic proteinase gene has an intron within its coding region and that it has a preproenzyme sequence of 66 amino acids upstream of the mature enzyme of 323 amino acids.
