additional information while the enzyme has extremely broad substrate specificity, some preferences are observed; the enzyme does not accept highly charged amino acids such as Lys, Arg, Glu, and Asp. The enzyme does not react with secondary amines such as Pro. The N-terminal residue of the dipeptide formed seems to be limited to Ala, Gly, Ser, Thr, and Met whereas the C-terminal residue seems to allow for a wider array of amino acids; and Ala and Ser seems to be most preferred for the N-terminal residue while Met and Phe seems to be preferred for the C-terminus. The enzyme does not react with D-Ala, D-serine, or D-phenylalanine Bacillus subtilis ?
