Function
MALE_ECOLI Involved in the high-affinity maltose membrane transport system MalEFGK. Initial receptor for the active transport of and chemotaxis toward maltooligosaccharides.CMD1_CHLRE Dioxygenase that catalyzes DNA modification by mediating the conversion of the modified genomic base 5-methylcytosine (5mC) into 5-glyceryl-methylcytosine (5gmC) (PubMed:31043749, PubMed:33531488). Catalyzes the conjugation of a glyceryl moiety from L-ascorbate (vitamin C) to the methyl group of 5mC through a carbon-carbon bond (PubMed:31043749, PubMed:33531488). 5gmC DNA modification may be required during photosynthesis as an epigenetic mark that couteracts DNA methylation (PubMed:31043749).[1] [2]
