?
small membrane protein Members of this family, including paralogs KPN_01023 and KPN_01923 from Klebsiella pneumoniae subsp. pneumoniae MGH 78578, are small proteins, typically 40 amino acids in length. A highly hydrophobic region, about 25 amino acids in length with a composition typical of transmembrane segments, is followed by a highly basic region of about 15 amino acids. Analogous proteins of similar size, with apparently similar hydrophobic regions, have been described as membrane-associated proteins expressed in response to various types of cell envelope stress. |
