Ornithine delta-aminotransferase mutations in gyrate atrophy. Allelic heterogeneity and functional consequences.
-
OAT is a nuclear-encoded mitochondrial matrix enzyme catalyzing the reversible interconversion of ornithine + alpha-ketoglutarate and glutamate semialdehyde + glutamate; site-directed mutagenesis of gyrate-atrophy alleles inactivates the enzyme.

Functional analysis of missense mutations of OAT, causing gyrate atrophy of choroid and retina.
-
The study describes OAT as homohexameric and finds loss of activity, instability or assembly defects in disease mutants; later human solution/kinetic studies establish active dimers and tetramer–dimer equilibrium, so its assembly description is not a universal stoichiometric requirement.

Point mutation affecting processing of the ornithine aminotransferase precursor protein in gyrate atrophy.
-
A generalized deficiency of the mitochondrial enzyme OAT is the inborn error in gyrate atrophy, a degenerative disease of the choroid and retina that leads to blindness.
