    Glutamate mutase (Glm) equilibrates (S)-glutamate with (2S,3S)-3-methylaspartate. Catalysis proceeds with the homolytic cleavage of the organometallic bond of the cofactor to yield a 5'-desoxyadenosyl radical. This radical then abstracts a hydrogen atom from the protein-bound substrate to initiate the rearrangement reaction. Glm from Clostridium cochlearium is a heterotetrameric molecule consisting of two sigma and two epsilon polypeptide chains.
