We have demonstrated that gramicidin S synthetase 1 (GS 1), phenylalanine racemase [EC 5.1.1.11], of Bacillus brevis catalyzes the exchange between a proton in the medium and alpha-hydrogen of phenylalanine in the course of the racemase reaction by using tritiated water or L-phenyl[2,3-3H]alanine. GS 1 from some gramicidin S non-producing mutants of B. brevis lacking phenylalanine racemase activity did not catalyze the tritium exchange reaction. The proton exchange between phenylalanine bound… CONTINUE READING
