In [[enzymology]], an '''arginine racemase''' ({{EC number|5.1.1.9}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:L-arginine <math>\rightleftharpoons</math> D-arginine

Hence, this enzyme has one [[substrate (biochemistry)|substrate]], L-[[arginine]], and one [[product (chemistry)|product]], D-[[arginine]].

This enzyme belongs to the family of [[isomerase]]s, specifically those [[racemase]]s and [[epimerase]]s acting on [[amino acid]]s and derivatives.  The systematic name of this enzyme class is '''arginine racemase'''. This enzyme participates in 3 [[metabolism|metabolic pathways]]: [[lysine degradation]], D-[[glutamine]] and D-[[glutamate]] metabolism, and D-[[arginine]] and D-[[ornithine]] metabolism.  It employs one [[cofactor (biochemistry)|cofactor]], [[pyridoxal phosphate]].
