Protein Family Models

The cupredoxin-like fold consists of a beta-sandwich with 7 strands in 2 beta-sheets, which is arranged in a Greek-key beta-barrel. (from Pfam)

This family is structurally different from the alpha/beta hydrolase family (Pfam:PF00561). This family includes L-2-haloacid dehalogenase, epoxide hydrolases and phosphatases. The structure of the family consists of two domains. One is an inserted four helix bundle, which is the least well conserved region of the alignment, between residues 16 and 96 of Swiss:P24069. The rest of the fold is composed of the core alpha/beta domain [1]. Those members with the characteristic DxD triad at the N-terminus are probably phosphatidylglycerolphosphate (PGP) phosphatases involved in cardiolipin biosynthesis in the mitochondria [2].

Members of this P-type ATPase family apparently include both Cu(+) (EC 3.6.3.54) and Cu(2+) (EC 3.6.3.4) copper efflux transporters.

The P-type ATPases are a large family of trans-membrane transporters acting on charged substances. The distinguishing feature of the family is the formation of a phosphorylated intermediate (aspartyl-phosphate) during the course of the reaction. P-type ATPases typically consist of only a single subunit encompassing the ATPase and ion translocation pathway, but these functions are split in some systems. The catalytic core of a P-type ATPase is a haloacid dehalogenase(HAD)-type aspartate-nucleophile hydrolase. The location of the ATP-binding loop in between the first and second HAD conserved catalytic motifs defines these enzymes as members of subfamily I of the HAD superfamily (see also TIGR01493, TIGR01509, TIGR01549, TIGR01544 and TIGR01545). Based on these classifications, the P-type ATPase _superfamily_ corresponds to the IC subfamily of the HAD superfamily.

This HMM encompasses two equivalog models for the copper and cadmium-type heavy metal transporting P-type ATPases (TIGR01511 and TIGR01512) as well as those species which score ambiguously between both models. For more comments and references, see the files on TIGR01511 and 01512.
