... DAOCS arginine mutations reported in this paper fall into three types. Some mutations prevent or seriously hinder productive penicillin (prime) substrate binding to the enzyme (arginines 160, ... loss of the penicillin substrate before oxidation. Penicillin substrate binding to DAOCS The results in this paper give support to the proposed mode of penicillin binding by DAOCS [1,12]...

... providing protons to the flavin ring to produce the hydroquinone form upon reduction of the enzyme when E301 is not present to provide them. Replacement of E301 by Ala also shifts the binding energy ... E312 (equivalent to E301 in Anabaena FNR) is displaced towards S96 (S80), bringing both side-chains into H-bonding distance [9]. In the Anabaena complex, changes are observed in...
