Histidine racemate is a mixture of naturally occurring essential amino acid L-histidine and its enantiomer D-histidine. D-histidine is less readily utilized than the natural isomer. It is not metabolized by histidase and is not readily oxidized by D-amino acid oxidase. Some fungi incorporate D-histidine into proteins as a measure of protection against hydrolases and to enhance antimicrobial activity.
