Human red-cell acid phosphatase (ACP1): a new mutant (ACP1*KUK) detected by isoelectric focusing, kinetics of thermostability and substrate activity.
A new rare mutant of the red-cell acid phosphatase (ACP1) is described using conventional gel electrophoresis and isoelectric focusing migration. According to the electrophoretic patterns obtained, the new mutant ACP1* KUK is different from the ACP* H and ACP1* A' variants already described. The enzyme activities and the thermostability curves definitively confirm the existence of a new variant. The transmission of this mutant was followed through a pedigree of three generations. The family originated from Czechoslovakia. The frequency of the variant is probably less than 0.001.
