| description | Two types of dihydroxyacetone kinase (glycerone kinase) are described. In yeast and a few bacteria, e.g. Citrobacter freundii, the enzyme is a single chain that uses ATP as phosphoryl donor and is designated . By contract, Escherichia coli and many other bacterial species have a multisubunit form with a phosphoprotein donor related to PTS transport proteins. This family represents a protein, unique to the firmicutes (low GC Gram-positives), that appears to be a divergent second copy of the K subunit of that complex; its gene is always found in operons with the other three proteins of the complex.This entry also includes DhaKLM operon coactivator DhaQ from Streptococcus lactis. It forms a heterotetramer with DhaS and functions as a transcriptional regulator []. |
