CYTME2 — Zea mays

Summary

ZM00001EB285890, designated CYTME2 on maize chromosome 6, encodes a protein with malic enzyme domains and malic enzyme activity, malate dehydrogenase (decarboxylating) (NAD+) activity, malate dehydrogenase (decarboxylating) (NADP+) activity, and oxaloacetate decarboxylase activity (EC 1.1.1.40), and is associated with NAD binding, metal ion binding, microtubule binding, and protein homodimerization activity. The gene is associated with NADP-malic enzyme C4 photosynthesis, regulation of gluconeogenesis, phloem loading, malate transport, and responses to crowding and light absorption. It localises to mitochondria, plastids, cytosol, plasmodesmata and the apoplast. CYTME2 is linked to leaf nitrogen content, specific leaf area, carbon isotope discrimination, rubisco content, chlorophyll content, net photosynthetic rate, water use efficiency, heat and cold tolerance, biomass yield, root length, and stomatal regulation. Related genes in other species are linked to salt stress tolerance, primary metabolism, and allosteric regulation.
