Overview

Basic information about this protein and its source genome.

Accession: KP13_05281
Assembly: Klebsiella pneumoniae subsp. pneumoniae Kp13, complete sequence
Gene: AHE44688.1
Status: annotated
Amino acids: 232
Structure source: AlphaFold + ColabFold

GO:0005524 Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. GO:0016887 Catalysis of the reaction: ATP + H2O = ADP + H+ phosphate. ATP hydrolysis is used in some reactions as an energy source, for example to catalyze a reaction or drive transport against a concentration gradient. GO:0015658 Enables the transfer of branched-chain amino acids from one side of a membrane to the other. Branched-chain amino acids are amino acids with a branched carbon skeleton without rings. GO:0015807 The directed movement of L-enantiomer amino acids into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

Ligand evidence

Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.

62 records

Highest-confidence structural evidence: ligands co-crystallized with this exact protein. If the source PDB is loaded in TPW, use Open crystal to inspect it in the structure viewer.

No PDB structure with a co-crystallized ligand found for this exact protein.

Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
