Overview

Basic information about this protein and its source genome.

Accession: KP13_01080
Assembly: Klebsiella pneumoniae subsp. pneumoniae Kp13, complete sequence
Gene: AHE42527.1 diaA
Status: annotated
Amino acids: 196
Structure source: AlphaFold + ColabFold

GO:1901135 The chemical reactions and pathways involving carbohydrate derivative. GO:0097367 Binding to a carbohydrate derivative. GO:0016853 Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5. GO:0006260 The cellular metabolic process in which a cell duplicates one or more molecules of DNA. DNA replication begins when specific sequences, known as origins of replication, are recognized and bound by the origin recognition complex, and ends when the original DNA molecule has been completely duplicated and the copies topologically separated. The unit of replication usually corresponds to the genome of the cell, an organelle, or a virus. The template for replication can either be an existing DNA molecule or RNA.

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.

51 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.
