P-type phospholipid transporter
WebDec 2, 2024 · The distinctive feature of Gram-negative bacteria is the presence of an asymmetric outer membrane (OM), which acts as a permeation barrier blocking the diffusion of noxious components such as antibiotics that could compromise cell survival. The outer membrane has an inner leaflet, mainly formed by phospholipids (PLs), and the outer …

WebP4-ATPases are a subfamily of P-type ATPases that transport specific phospholipids from the exoplasmic to the cytoplasmic leaflet of membranes to generate and maintain membrane lipid asymmetry ( Tang et al., 1996; Coleman et al., 2009; Zhou and Graham, 2009 ). WebFIC1, a P-type ATPase linked to cholestatic liver disease, has homologues (ATP8B2 and ATP8B3) expressed throughout the body. 12880872. ...

WebMar 5, 2024 · Scramblases are ATP-independent transporters that transport negatively charged phospholipids in either direction across the membrane. Humans express 14 flippase and floppase genes, all of which are members of the ATPase family of membrane transporters, specifically the ATP8, ATP9, ATP10, and ATP11 subfamilies. WebP-type ATPases are α-helical bundle primary transporters named based upon their ability to catalyze auto- (or self-) phosphorylation (hence P) of a key conserved aspartate residue within the pump and their energy source, …
In addition to the subfamilies of P-type ATPases listed above, several prokaryotic families of unknown function have been identified. The Transporter Classification Database provides a representative list of members of the P-ATPase superfamily, which as of early 2016 consisting of 20 families. Members of the P-ATPase superfamily are found in bacteria, archaea and eukaryotes.
