exosortase family protein XrtM Members of this family, part of the larger exosortase/archaeosortase family, are known from five related cassettes of genes in Methylomonas methanica MC09, a gammaproteobacterial methanotroph. Each xrtM gene occurs near a large YD repeat (see TIGR01643) protein of 1500-2500 residues and a small, uncharacterized protein of about 200 residues. No PEP-CTERM-like recognition sequence has been identified, so this protein is designated as exosortase family, but not necessarily a functional exosortase. |
