Comments
Comments inorganic cation transport ATPase [PUB_0110]; possibly transports calcium [PUB_096,PUB_0211]; Flavobacterium odoratum p-type calcium atpase is homologous to eukaryotic sarcoplasmic reticulum p-type calcium atpase [PUB_0213]; sacroplasmic calcium p-type atpase may be catalytically active as a monomer [PUB_0214]. Gambel et al observed MgtA kinetic rate of 10 nmol/min mg protein [PUB_0212].
