Protein of unknown function (DUF1343). This family consists of several hypothetical bacterial proteins of around 400 residues in length. The function of this family is unknown.
AMIN domain. This N-terminal domain of various bacterial protein families is crucial for the targetting of periplasmic or extracellular proteins to specific regions of the bacterial envelope. AMIN is derived from the N-terminal domain of AmiC, an N-acetylmuramoyl-l-alanine amidase of Escherichia coli which localizes to the septal ring during division and plays a key role in the separation of daughter cells. The AMIN domain is present in several protein families besides amidases suggesting that AMIN may represent a general targetting determinant involved in the localization of periplasmic protein complexes.
