Molecular characterization of a novel beta1,3-galactosyltransferase for capsular polysaccharide synthesis by Streptococcus agalactiae type Ib.

abstract：:1. When ribonuclease T1 [EC 3.1.4.8] (0.125% solution) was treated with a 760-fold molar excess of iodoacetamide at pH 8.0 and 37 degrees, about 90% of the original activity was lost in 24 hr. The half-life of the activity was about 8 hr. The binding ability for 3'-GMP was lost simultaneously. Changes were detected on...
