Web1. dec 1993 · Periplasmic binding protein-dependent transport systems represent a common mechanism for nutrient and ion uptake in bacteria. As a group, these systems are related to one another and to other transporters of both prokaryotes and eukaryotes, based on sequence similarity within an ATP-binding subunit and overall structural organization. WebAn insertion in accA, which encodes the periplasmic binding protein for agrocinopines A+B, abolished chemotaxis while an insertion in accC, which encodes a component of the transport system, and an insertion in accF, which encodes a function required for agrocinopine catabolism, did not affect chemotaxis to this opine.

Web5. feb 2013 · These proteins named periplasmic binding proteins (PBPs) interact and associate with extreme specificity and affinity with different substrates that are distributed to the appropriate ABC transporter anchored to the inner membrane. WebStructurally, H. pylori CeuE belongs to the class III periplasmic substrate-binding protein. Both crystallographic data and fluorescence binding assays allow to exclude a role of the protein in the transport of Vitamin B12, enterobactin, haem and isolated Ni(2+) ions. chive seeds planting

Web30. nov 2024 · Introduction. Periplasmic-binding proteins (PBPs) are a large family of structurally related proteins that bind diverse ligands from ions to saccharides to aminoacids for their import into gram-negative bacteria [].PBPs are composed of two domains that open and close around a hinge and this motion is a paradigm of large … WebInterPro provides functional analysis of proteins by classifying them into families and predicting domains and important sites. We combine protein signatures from a number of member databases into a single searchable resource, capitalising on their individual strengths to produce a powerful integrated database and diagnostic tool.
