TextSentencer_T1 0-102 Sentence denotes A bireactant, irreversible, active-site-directed inhibitor of beta-D-galactosidase (Escherichia coli).
TextSentencer_T2 103-188 Sentence denotes Synthesis and properties of (1/2,5,6)-2-(3-azibutylthio)-5,6-epoxy-3-cyclohexen-1-ol.
TextSentencer_T3 189-347 Sentence denotes (1/2,5,6)-2-(3-Azibutylthio)-5,6-epoxy-3-cyclohexen-1-ol (1) was synthesized and was found to irreversibly inactivate beta-D-galactosidase (Escherichia coli).
TextSentencer_T4 348-447 Sentence denotes The inactivation was prevented by the presence of isopropyl 1-thio-beta-D-galactopyranoside (IPTG).
TextSentencer_T5 448-550 Sentence denotes The vinyloxirane group of 1 reacted with water and other nucleophiles, especially at higher pH values.
TextSentencer_T6 551-682 Sentence denotes Reaction of 1 with beta-D-galactosidase was slow enough so that a competitive-inhibition constant (Ki) of 29mM could be determined.
TextSentencer_T7 683-984 Sentence denotes The inhibition constant for (1,2/3,6)-6-(3-azibutylthio)-2-bromo-4-cyclohexene-1,3-diol (2), the precursor of the bireactant inhibitor 1, was 13 mM, while that of (1,3/2,4)-3-(3-azibutylthio)-5-cyclohexene-1,2,4-triol (3), the product formed when the reactant is allowed to react with water, was 23mM.
TextSentencer_T8 985-1261 Sentence denotes After irradiation by light, beta-D-galactosidase that had initially been treated with the bireactant compound and then digested with trypsin, showed a new pattern of elution from h.p.l.c., indicating that there was reaction at two regions of the beta-D-galactosidase molecule.
