127-212 9.45e-44

Opacity-associated protein A LysM-like domain; The OapA domain gets its name from the Haemophilus influenzae protein OapA, which is required for the expression of colony opacity, thus opacity- associated protein A. The OapA protein is required for efficient nasopharyngeal mucosal colonization, and its expression is associated with a distinctive transparent colony phenotype. OapA is thought to be a secreted protein, and its expression exhibits high-frequency phase variation. The OapA domain has been shown to bind to peptidoglycan in the E. coli protein YtfB. A screen to identify factors that affect cell division in E. coli discovered that overproducing a fragment of YtfB, including its OapA domain, caused cells to grow as long filaments. OapA domains are commonly associated with other domains that are involved in breaking peptidoglycan cross-links. The OapA domain is distantly related to pfam01476.

Opacity-associated protein A N-terminal motif; This family includes the Haemophilus influenzae opacity-associated protein. This protein is required for efficient nasopharyngeal mucosal colonization, and its expression is associated with a distinctive transparent colony phenotype. OapA is thought to be a secreted protein, and its expression exhibits high-frequency phase variation. This motif occurs at the N-terminus of these proteins. It contains a conserved histidine followed by a run of hydrophobic residues.
