6s6zA Structure of beta-galactosidase from thermotoga maritima (see paper)

P00722 Beta-galactosidase; Beta-gal; Lactase; EC 3.2.1.23 from Escherichia coli (strain K12) (see 13 papers)
33% identity, 94% coverage: 49:1080/1101 of query aligns to 17:1019/1024 of P00722
- D202 (= D236) mutation D->E,N: Causes a significant decrease in binding affinity in the absence of monovalent cations or in the presence of potassium ions, but only a moderate decrease in the presence of sodium ions.; mutation to F: Obliterates all binding and catalysis.
- H358 (= H402) mutation H->D,F,L,N: Less stable to heat than wild-type. Causes significant destabilizations of the first transition state.
- H392 (= H436) mutation H->E,F,K: Essentially inactive unless very rapid purification. Causes very large destabilizations of the transition state.
- E417 (= E461) binding Mg(2+)
- H419 (= H463) binding Mg(2+)
- E462 (= E504) active site, Proton donor; binding Mg(2+); mutation to H: Slowly inactivates galactosidase activity by reducing the binding of magnesium. It increases binding specificity.
- E538 (= E598) active site, Nucleophile; mutation to Q: 10000-fold decrease in the beta-galactosidase activity.
- H541 (= H601) mutation H->E,F,N: Poorly reactive with galactosyl substrates. Less stable to heat than wild-type.
- N598 (≠ H659) binding Mg(2+)
- F602 (= F663) mutation to A: Decreases the stability of the loop 794-804.
- G795 (vs. gap) mutation to A: It forces the apoenzyme to adopt the closed rather than the open conformation. Reduces the binding affinity.
- E798 (vs. gap) mutation E->A,L: The catalytic efficiency is not increased, when the sodium concentration increases.; mutation E->D,Q: Small increase of the catalytic efficiency, when the sodium concentration increases.
- W1000 (= W1059) mutation W->F,G,L,T: Decreases affinity for substrate.
