Phylogenetic approach for inferring the origin and functional evolution of bacterial ADP-ribosylation superfamily.

abstract：BACKGROUND:A core sequence (the 9 C-terminal residues) of calcification-associated peptide (CAP- 1) isolated from the exoskeleton of the red swamp crayfish was previously shown to control calcium carbonate precipitation with chitin. In addition, a modified core sequence in which the phosphorylated serine at the N termi...
