Overview

Basic information about this protein and its source genome.

Accession: PA3250
Assembly: Pseudomonas aeruginosa PAO1, complete genome
Gene: PA3250
Status: annotated
Amino acids: 352
Structure source: AlphaFold

GO:0030288 The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall. GO:0030975 Binding to thiamine (vitamin B1), a water soluble vitamin present in fresh vegetables and meats, especially liver. GO:0030976 Binding to thiamine pyrophosphate, the diphosphoric ester of thiamine. Acts as a coenzyme of several (de)carboxylases, transketolases, and alpha-oxoacid dehydrogenases. GO:0015888 The directed movement of thiamine into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Thiamine is vitamin B1, a water soluble vitamin present in fresh vegetables and meats, especially liver.

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.

53 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.
