A novel enzyme immunoassay (immune complex transfer enzyme immunoassay) for anti-thyroglobulin IgG using beta-D-galactosidase from Escherichia coli as label was reported previously. This immunoassay was highly sensitive in demonstrating anti-thyroglobulin IgG not only in all patients with Graves' di

✦ Synopsis
Through the use of a series of N-substituted (B-o-galactopyranosylmethyl)amines @Gal-CH,NHR) and the corresponding N-substituted C-(P-u-galactopyranosyl)formamides @Gal-CO-NHR), it has been determined that the inhibitor binding constant is influenced more by the pK, of the amine group than by the nature of the hydrophobic group. It is concluded that the compounds that are the best inhibitors are those which allow proton donation in the active site to form an ion

## Abstract 2,4‐Dinitrophenyl‐1‐thio __N__‐acetyl‐β‐D‐glucosaminide was examined as a new substrate for analyzing the level of __N__‐acetyl‐β‐D‐glucosaminidase in the urine of patients suffering from renal diseases. The analysis is based on the fact that the substrate, when hydrolyzed in the presen
Nucleophiles activated the catalytic actions of P-galactosidases with neutral or positively charged substitutions for Glu-461. Aliphatic carboxylic acids increased the rate of hydrolysis of o-nitrophenyl P-o-galactopyranoside if the pKa values of the carboxyl groups were > -3.5. Amino compounds acti
