Heterologous expression of cDNAs encoding monodehydroascorbate reductases from the moss, Physcomitrella patens and characterization of the expressed enzymes

Monodehydroascorbate reductase (MDHAR; EC catalyses the reduction of the monodehydroascorbate (MDHA) radical to ascorbate, using NADH or NADPH as an electron donor, and is believed to be involved in maintaining the reactive oxygen scavenging capability of plant cells. This key enzyme in the ascorbate-glutathione cycle has been studied here in the… (More)
