== Function ==
[https://www.uniprot.org/uniprot/MALE_ECOLI MALE_ECOLI] Involved in the high-affinity maltose membrane transport system MalEFGK. Initial receptor for the active transport of and chemotaxis toward maltooligosaccharides.[https://www.uniprot.org/uniprot/CMD1_CHLRE 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).<ref>PMID:31043749</ref> <ref>PMID:33531488</ref>
