ABSTRACT
The protein encoded by the NCE103 gene of Candida glabrata, a beta-carbonic anhydrase (CA, EC 4.2.1.1) designated as CgCA, was investigated for its activation with amines and amino acids. CgCA was weakly activated by amino acids such as l-/d-His, l-Phe, l-DOPA, and l-Trp and by histamine or dopamine (K(A)s of 21.2-37microM) but more effectively activated by d-Phe, d-DOPA, d-Trp as well as serotonin, pyridyl-alkylamines, aminoethyl-piperazine/morpholine (K(A)s of 10.1-16.7microM). The best activators were l-/d-Tyr, with activation constants of 7.1-9.5microM. This study may bring a better understanding of the catalytic/activation mechanisms of beta-CAs from pathogenic fungi.
