Cloning and Expression of the Pyridoxal 5-Phosphate pdf moonlighting function of glutamate racemase from

Abstract. d-Aspartate is present at high concentrations in the tissues of Scapharca broughtonii, and its production depends on aspartate racemase.This enzyme is the first aspartate racemase purified from animal tissues and unique in its pyridoxal 5-phosphate (PLP)dependence in contrast to microbial aspartate racemases thus far characterized.Chlamydia trachomatis dapF Encodes a Bifunctional pyridoxal phosphate-dependent racemization of glutamate. Enzyme promiscuity is thought to be the hallmark of early microbial life on this planet, and there is cur-rently an active debate as to whether moonlighting enzymes represent primordial evolutionary relics or are a product of more recent reductionist evolutionary pres-sures.Chlamydia trachomatis dapF Encodes a Bifunctional pyridoxal phosphate-dependent racemization of glutamate.
