Abstract
A procedure for isolation and purification of aspartate aminotransferase from wheat grain includes chromatography on DEAE cellulose, acidification–alkalization, precipitation with protamine sulfate, fractionation with ammonium sulfate, and chromatography on hydroxyapatite. The yield of protein was 27% with 95% purity. Crystals of the enzyme (0.05 × 0.025 × 0.015 mm3) were obtained from ammonium sulfate solution.
