3.5.2.10 | crystal structure of the enzyme complexed with a 1-methylguanidine. All subunits in the complex exist as the closed form. X-ray crystallographic study and the atomic absorption spectrometry analysis of the E122Q mutant-substrate complex reveal that the drastic decrease of the activity of the E122Q is caused by the loss of one Zn ion at the Metal1 site and a critical function of Glu122 | Pseudomonas putida |
