CLEC-Subtilisin efficiently catalyzed the synthesis of optically active alkylamides of amino acids and peptides. The high enantioselectivity of the catalyst toward L-amino acids and S-amines resulted in formation of the S,S-alkylamide regardless of the optical purity of the substrates. The catalyst accepts a broad range of substrates, including peptides, natural and unnatural amino acids. The acyl
CLEC-枯草杆菌蛋白酶有效催化氨基酸和肽的光学活性烷基酰胺的合成。催化剂对L-氨基酸和S-胺的高对映选择性导致形成S,S-烷基酰胺,而与底物的光学纯度无关。该催化剂接受多种底物,包括肽,天然和非天然氨基酸。酰基供体可以是甲基,乙基或苄基酯。酰基供体的N-保护基可以是乙酰基,Boc或Cbz。
