Overview

Basic information about this protein and its source genome.

Accession: KP13_01468
Assembly: Klebsiella pneumoniae subsp. pneumoniae Kp13, complete sequence
Gene: AHE43998.1
Status: annotated
Amino acids: 559
Structure source: AlphaFold + ColabFold

GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:0008272 OBSOLETE. The directed movement of sulfate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. GO:0055085 The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other. GO:0008271 Enables the secondary active transfer of sulfate from one side of a membrane to the other. Secondary active transport is the transfer of a solute across a membrane, up its concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction and is driven by a chemiosmotic source of energy. Secondary active transporters include symporters and antiporters. GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
