RT "The role of metalloproteases (leupeptin-inactivating enzymes) in
RT morphological differentiation of Streptomyces exfoliatus SMF13.";
RL Submitted (JUL-2003) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: A leucine-specific metalloprotease that plays a role in
CC controlling the amount of leupeptin during colony development. Degrades
CC leupeptin into three components, acetyl-leucine, leucine and argininal
CC (By similarity). {ECO:0000250|UniProtKB:P81715}.
CC -!- COFACTOR:
