the D154N mutation results in a prominant increase in cell viability after freezing at -20°C compared to the viability of the cells harboring the wild-type PRO1 gene, method for breeding novel freeze-tolerant yeast strains
G5K and the homologous acetylglutamate kinase closely resemble each other concerning substrate binding and catalysis, but that they have different mechanisms of feed-back control, roles of K10, K217 and T169 in catalysis and ATP binding and of D150 in orienting the catalytic lysines, roles of D148 and D150 in glutamate binding and of D148 and N149 in proline binding
