Provides input for
Overview and Scope of Use
- This relation is used in GO-CAMs but not in standard annotation extensions.
- This relation is intended to connect successive enzymatic reactions in a pathway, i.e. where the product of the upstream activity is the substrate for the downstream activity.
- The 'directly provides input for' relation is used to relate two GO Molecular Functions when:
- Two Molecular Functions succeed one another directly
- The output of the first molecular function is an input of the second Molecular Function.
The 'directly provides input for' relation is most commonly used between successive steps of a metabolic pathway.
Annotation Usage Guidelines
- Standard Annotation
- 'directly provides input for' should not be used for conventional annotations. Instead its use should be reserved for GO-CAM models.
- GO-CAM Annotation
- 'directly provides input' should be reserved to related successive Molecular Functions in GO-CAM models.
- Usage Examples
- In glycolysis, triose phosphate isomerase activity (MF) 'directly provides input for' glyceraldehyde-3-phosphate dehydrogenase (NAD+) (phosphorylating) activity (MF).
- triose phosphate isomerase activity converts dihydroxyacetone phosphate (input) to glyceraldehyde-3-phosphate (output) as part of glycolysis. Glyceraldehyde-3-phosphate dehydrogenase converts glyceraldehyde-3-phosphate (input) to 3-phosphonato-D-glyceroyl phosphate(4−) (output).

- A glucose tansmembrane transporter activity (MF) 'directly provides input for' lactose synthase activity (MF).
- cytosolic glucose (input) is transported across the Golgi membrane to become Golgi-lumenal glucose (output). In the Golgi lumen the Golgi-lumenal glucose (input) is converted into lactose (output).
