Prophage CP4-57 regulatory protein (AlpA); This family consists of several short bacterial and phage proteins which are related to the E. coli protein AlpA. AlpA suppress two phenotypes of a delta lon protease mutant, overproduction of capsular polysaccharide and sensitivity to UV light. Several of the sequences in this family are thought to be DNA-binding proteins.

 20-61 8.72e-04

DNA binding domain, excisionase family; An excisionase, or Xis protein, is a small protein that binds and promotes excisive recombination; it is not enzymatically active. This model represents a number of putative excisionases and related proteins from temperate phage, plasmids, and transposons, as well as DNA binding domains of other proteins, such as a DNA modification methylase. This model identifies mostly small proteins and N-terminal regions of large proteins, but some proteins appear to have two copies. This domain appears similar, in both sequence and predicted secondary structure (PSIPRED) to the MerR family of transcriptional regulators (pfam00376). [Unknown function, General]
