1.2.1.12 additional information - comparison of structural properties 287976 1.2.1.12 additional information - Cys content is higher than that found in analogous enzymes 287961 1.2.1.12 additional information - high content of beta-structure, 45% 287974 1.2.1.12 additional information - the enzyme possesses precise 222 symmetry. Pairs of active sites are linked through a flexible polypeptide loop which probably mediates the structural changes giving rise to cooperative effects. Three additional salt bridges made by each subunit to others would make a major contribution to thermostability of the tetramer 287962 1.2.1.12 additional information - unusually low His content compared to other mammalian muscle acetaldehyde phosphate dehydrogenases 287960 1.2.1.12 14000 - x * 14000 + x * 37000, SDS-PAGE 287961 1.2.1.12 29500 - 4 * 29500, enzyme form E8.5, SDS-PAGE 287913 1.2.1.12 33000 - 4 * 33000, enzyme form E9.5, SDS-PAGE 287913 1.2.1.12 33500 - 4 * 33500, cytosolic enzyme, SDS-PAGE 287901 1.2.1.12 33500 - 4 * 33500, SDS-PAGE 287938
