COMMENT     A subtilisin homologue, not containing cysteine, that is the
            predominant extracellular alkaline endopeptidase of the mould
            Aspergillus oryzae.  Formerly EC 3.4.21.15, and included in
            EC 3.4.21.14.  Identical or closely related enzymes are produced
            by A. flavus and A. sojae.
