摘要

N10-methylfolate acted as a potent competitive inhibitor of high-affinity [3H] folate binding in human leukocytes, while methotrexate had no effect. Furthermore, folate binding changed into a non-cooperative type in the presence of N10-methylfolate. Hence, in qualitative and quantitative respects, the substrate specificity characteristics of leukocyte folate binding resemble those of other high-affinity folate binding systems.
