ABC transporter, phosphonate import, PhnC (IPR012693)

Short name: ABC_transpr_PhnC

Family relationships



The ATP-Binding Cassette (ABC) superfamily forms one of the largest of all protein families with a diversity of physiological functions [PMID: 9873074]. Several studies have shown that there is a correlation between the functional characterisation and the phylogenetic classification of the ABC cassette [PMID: 9873074, PMID: 11421270]. More than 50 subfamilies have been described based on a phylogenetic and functional classification [PMID: 9873074, PMID: 11421269, PMID: 11421270].

Members of this protein family are the ABC transporters of phosphonates. Phosphonates are a class of phosphorus-containing organic compound with a stable direct C-P bond rather than a C-O-P linkage. A number of bacterial species have operons, typically about 14 genes in size, with genes for ATP-dependent transport of phosphonates, degradation, and regulation of the expression of the system.
