Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Part of the ABC transporter complex MppA-OppBCDF involved in the uptake of the cell wall murein tripeptide L-alanyl-gamma-D-glutamyl-meso-diaminopimelate (PubMed:9495761). Is involved in the recycling of cell wall peptides (PubMed:9495761). Binds the cell wall peptide L-Ala-D-Gly-gamma-meso-diaminopimelic acid (PubMed:21705338, PubMed:9495761). Can also transport ordinary alpha-linked tripeptides such as Pro-Phe-Lys, but with much lower efficiency than OppA (PubMed:9495761). Cannot bind typical tripeptides such as Lys-Glu-Lys, Lys-Lys-Lys or Ala-Ala-Ala (PubMed:21705338).SUBUNIT The complex is composed of two ATP-binding proteins (OppD and OppF), two transmembrane proteins (OppB and OppC) and a solute-binding protein (MppA).SUBCELLULAR LOCATION Belongs to the bacterial solute-binding protein 5 family.
