RT "Complete genome sequence of Schizopora paradoxa KUC8140, a cosmopolitan
RT wood degrader in East Asia.";
RL Submitted (APR-2015) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Has aminopeptidase activity, shortening substrate peptides
CC sequentially by 1 amino acid. Has bleomycin hydrolase activity, which
CC can protect the cell from the toxic effects of bleomycin. Has
CC homocysteine-thiolactonase activity, protecting the cell against
CC homocysteine toxicity. {ECO:0000256|PIRNR:PIRNR005700}.
CC -!- FUNCTION: The normal physiological role of the enzyme is unknown, but
CC it is not essential for the viability of yeast cells. Has
CC aminopeptidase activity, shortening substrate peptides sequentially by
CC 1 amino acid. Has bleomycin hydrolase activity, which can protect the
CC cell from the toxic effects of bleomycin. Has homocysteine-
CC thiolactonase activity, protecting the cell against homocysteine
CC toxicity. Acts as a repressor in the GAL4 regulatory system, but this
CC does not require either the peptidase or nucleic acid-binding
CC activities. {ECO:0000256|ARBA:ARBA00025347}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Inactivates bleomycin B2 (a cytotoxic glycometallopeptide) by
CC hydrolysis of a carboxyamide bond of beta-aminoalanine, but also
CC shows general aminopeptidase activity. The specificity varies
CC somewhat with source, but amino acid arylamides of Met, Leu and Ala
CC are preferred.; EC=3.4.22.40;
CC Evidence={ECO:0000256|ARBA:ARBA00000423,
CC ECO:0000256|PIRNR:PIRNR005700};
CC -!- SUBUNIT: Homohexamer. Binds to nucleic acids. Binds single-stranded DNA
CC and RNA with higher affinity than double-stranded DNA.
CC {ECO:0000256|ARBA:ARBA00026080}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000256|PIRNR:PIRNR005700}.
CC Cytoplasm {ECO:0000256|PIRNR:PIRNR005700}.
CC -!- SIMILARITY: Belongs to the peptidase C1 family.
CC {ECO:0000256|PIRNR:PIRNR005700}.
