This model describes the LPXTG motif-containing region found at the C-terminus of many surface proteins of Streptococcus and Streptomyces species. Cleavage between the Thr and Gly by sortase or a related enzyme leads to covalent anchoring at the new C-terminal Thr to the cell wall. Hits that do not lie at the C-terminus or are not found in Gram-positive bacteria are probably false-positive. A common feature of this proteins containing this domain appears to be a high proportion of charged and zwitterionic residues immediatedly upstream of the LPXTG motif. This model differs from other descriptions of the LPXTG region by including a portion of that upstream charged region.

This repeat is found in proteins such as the biofilm-associated protein Bap of Acinetobacter baumannii (which can exceed 8000 amino acids in length), the calcium-stabilized ice-binding adhesin of the Antarctic bacterium Marinomonas primoryensis, and the giant calcium-binding adhesin SiiE of Salmonella enterica.
