1 l-Phe was a potent activator of isozymes I, II, and XIV (K(A)s of 13-240 nM), a weaker activator of hCA VA and VII (K(A)s of 9.8-10.9 microM), and a quite inefficient hCA IV activator (K(A) of 52 microM). Phenylalanine carbonic anhydrase 5A Homo sapiens
2 d-Phe showed good hCA II activatory properties (K(A) of 35 nM), being a moderate hCA VA, VII, and XIV (K(A)s of 4.6-9.7 microM) and a weak hCA I and IV activator (K(A)s of 63-86 microM). Phenylalanine carbonic anhydrase 5A Homo sapiens
