  • GO:0032993 A macromolecular complex containing both protein and DNA molecules.
  • GO:0001216 A DNA-binding transcription factor activity that activates or increases transcription of specific gene sets.
  • GO:0003950 Catalysis of the reaction: NAD+ + (ADP-D-ribosyl)(n)-acceptor = nicotinamide + (ADP-D-ribosyl)(n+1)-acceptor.
  • GO:0000976 Binding to a specific sequence of DNA that is part of a regulatory region that controls transcription of that section of the DNA. The transcribed region might be described as a gene, cistron, or operon.
  • GO:1900377 Any process that stops, prevents or reduces the frequency, rate or extent of secondary metabolite biosynthetic process.
  • GO:0045893 Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.
  • GO:0045862 Any process that activates or increases the frequency, rate or extent of the hydrolysis of a peptide bond or bonds within a protein.
  • GO:0006355 Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
  • GO:0003700 A transcription regulator activity that modulates transcription of gene sets via selective and non-covalent binding to a specific double-stranded genomic DNA sequence (sometimes referred to as a motif) within a cis-regulatory region. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons.

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.

58 records

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.
