| Abstract: | Partially purified beta-galactosidase of Xanthomonas campestris required 32 to 37 degrees C and pH 5.5 to 5.8 for optimum activity. The enzyme had low affinity for lactose hydrolysis (K(m) = 22 mM) and was inhibited by thiol group reagents, ethylenediaminetetraacetic acid, galactose, and d-galactal. |
