Two previously undetected variants of glutamic-pyruvic transaminase found by acidic polyacrylamide gel electrophoresis.
Two new electrophoretic variants of glutamic-pyruvic transaminase (GPT) have been found by polyacrylamide gel electrophoresis at acidic pH. They appeared to represent a single allele, GPT 2, by the standard method of starch gel electrophoresis. Studies in families show that they are inherited as codominant alleles at the GPT locus. Population frequencies are about the same as those of other rare GPT variants. Their behavior on gels is consistent with both of them having substitutions of histidines in place of uncharged amino acids.
