Penicillin acylase from E. coli (EC 3.5.1.11) accepts a broad range of N-phenylacetyl-dipeptide esters as substrates. The enzyme hydrolyses the N-terminal protecting group selectively at room temp. and pH=8.1 without affecting the peptide- or the ester-bonds. Alternatively methyl-, benzyl-, tert-butyl and allyl esters can be cleaved chemically leaving the phenylacetamido moiety intact.
来自大肠杆菌的青霉素酰基转移酶(EC 3.5.1.11)接受各种N-苯基乙酰基-二肽酯作为底物。该酶在室温下选择性水解N末端保护基。pH = 8.1,且不影响肽键或酯键。或者,可以化学裂解甲基,苄基,叔丁基和烯丙基酯,而使苯基乙酰胺基部分完整。
