Summary
Independent dimeric genes GOT-2 and GOT-4 determining activity for glutamate oxaloacetate transaminase (E.C.2.6.1.1; GOT) in zones GOT-II and GOT-IV respectively were identified. Three alleles were found for GOT-2 and two for GOT-4, including a null allele for GOT-2 which produced detectable heterodimeric bands but not homodimeric bands. Linkage studies with leucine aminopeptidase (E.C.3.4.11.1; LAP) genes suggested linkage of GOT-2 with LAP-2 (r=0.13±0.23) and GOT-4 with LAP-1 (r=0.10±0.40).
