- Display abstract
Phosphotransacetylases of Escherichia coli and several other bacteria contain an additional 350-aa N-terminal fragment that is not required forphosphotransacetylase activity. Sequence analysis of this fragment revealed that it is closely related to a family of ATP-dependent enzymes that also includesdethiobiotin synthetase and the synthetase domains of two amidotransferasesinvolved in cobalamin biosynthesis, cobyrinic acid a,c-diamide synthase (CobB)and cobyric acid synthase (CobQ). Further database searches showed that thisenzyme family is also related to the MinD family of ATPases involved inregulation of cell division in bacteria and archaea. Analysis of sequenceconservation in the members of this enzyme family using the structure ofdethiobiotin synthetase active site as a guide allowed us to suggest a model for the interaction of CobB and CobQ with their respective substrates. CobB and CobQ were also found to contain unusual Triad family (class I) glutamineamidotransferase domains with conserved Cys and His residues, but lacking the Gluresidue of the catalytic triad. These results should help in understanding theenzymology of cobalamin biosynthesis and in resolving the role ofphosphotransacetylase in regulation of the carbon flow to and from acetate.
