construction of enzyme structure with a closed active site by modifying the HAL structure including the L-cysteine inhibitor by replacement of the 39-80 loop containing the catalytically essential Tyr53, in every subunit of the homotetrameric enzyme. The most plausible reaction pathway involves the N-3,5-dihydro-5-methylidene-4H-imidazol-4-one intermediate structure in which the L-histidine substrate is covalently bound to the N-3,5-dihydro-5-methylidene-4H-imidazol-4-one prosthetic group of the apoenzyme via the amino group. Zn-complex formation plays a role in the reactivity and substrate specificity | Pseudomonas putida |
