Regulation of Glucokinase in Liver* *This review will be limited in scope to only the high Km glucose–ATP phosphotransferase found in liver of many animal species, and will dwell mainly on regulatory aspects. For a broader perspective on other hexokinase types, the reader is referred to the comprehensive review by Walker (165). Further material will be found in a recent review by Ureta (155a) on the phylogeny and ontogenesis of vertebrate hexokinase.
