Cesium 75-77 fructosamine 3 kinase Homo sapiens 0-4 28287856-2 2018 CS-0777, a candidate compound for autoimmune diseases, becomes phosphorylated active metabolite, M1, by fructosamine 3-kinase (FN3K), FN3K-related protein (FN3K-RP); and M1 is reverted back to CS-0777 by alkaline phosphatase (ALP) in the body. Cesium 0-2 fructosamine 3 kinase Homo sapiens 104-125 28287856-2 2018 CS-0777, a candidate compound for autoimmune diseases, becomes phosphorylated active metabolite, M1, by fructosamine 3-kinase (FN3K), FN3K-related protein (FN3K-RP); and M1 is reverted back to CS-0777 by alkaline phosphatase (ALP) in the body. Cesium 0-2 fructosamine 3 kinase Homo sapiens 127-131 28287856-2 2018 CS-0777, a candidate compound for autoimmune diseases, becomes phosphorylated active metabolite, M1, by fructosamine 3-kinase (FN3K), FN3K-related protein (FN3K-RP); and M1 is reverted back to CS-0777 by alkaline phosphatase (ALP) in the body. Cesium 193-195 fructosamine 3 kinase Homo sapiens 104-125 28287856-3 2018 We performed enzyme kinetic analysis of phosphorylation of CS-0777 by FN3K, FN3K-RP, human erythrocytes and human platelets; and dephosphorylation of M1 by various ALP isozymes and human liver, kidney, lung and small intestine microsomes. Cesium 59-61 fructosamine 3 kinase Homo sapiens 70-74 28287856-5 2018 The Michaelis constants of human FN3K, FN3K-RP and erythrocytes for CS-0777 phosphorylation were in the range from 498 muM to 1060 muM. Cesium 68-70 fructosamine 3 kinase Homo sapiens 33-37
