Biochemical Activity

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

The N-terminal domain of human holocarboxylase synthetase facilitates biotinylation via direct interaction with the substrate protein.

Lee CK, Cheong C, Jeon YH

Human holocarboxylase synthetase shows a high degree of sequence homology in the catalytic domain with bacterial biotin ligases such as Escherichia coli BirA, but differs in the length and sequence of the N-terminus. Despite several studies having been undertaken on the N-terminal region of hHCS, the role of this region remains unclear. We determined the structure of the N-terminal domain ... [more]

Co-crystal Structure

Interaction directly demonstrated at the atomic level by X-ray crystallography. Also used for NMR or Electron Microscopy (EM) structures. If there is no obvious bait-hit directionality to the interaction involving 3 or more proteins, then the co-crystallized proteins should be listed as a complex.
