>TIGR01681 HAD-SF-IIIC HAD-superfamily phosphatase, subfamily IIIC; InterPro: IPR010033 This entry represents the IIIC subfamily of the Haloacid Dehalogenase (HAD) superfamily of aspartate nucleophile hydrolases. Subfamily III, which includes subfamily IIIA (IPR006549 from INTERPRO) and subfamily IIIB (IPR005519 from INTERPRO) contains sequences which do not contain either of the insert domains between the 1st and 2nd conserved catalytic motifs, subfamily I (IPR006388 from INTERPRO, IPR006402 from INTERPRO, IPR006439 from INTERPRO, IPR006383 from INTERPRO, IPR006545 from INTERPRO, IPR006434 from INTERPRO, and IPR006435 from INTERPRO), or between the 2nd and 3rd, subfamily II (IPR006357 from INTERPRO, and IPR006379 from INTERPRO). Subfamily IIIC contains five relatively distantly related clades: a family of viral proteins (IPR007827 from INTERPRO), a family of eukaryotic proteins called MDP-1 and a family of archaeal proteins most closely related to MDP-1 (IPR010036 from INTERPRO), a family of bacteria including the Streptomyces FkbH protein (IPR010037 from INTERPRO), and a small clade including the Pasteurella multocida BcbF and EcbF proteins. The overall lack of species overlap among these clades may indicate a conserved function, but the degree of divergence between the clades and the differences in architecture outside of the domain in some clades warns against such a conclusion. No member of this subfamily is characterised with respect to function, however the MDP-1 protein is a characterised phosphatase. All of the characterised enzymes within subfamily III are phosphatases, and all of the active site residues characteristic of HAD-superfamily phosphatases are present in subfamily IIIC..
