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 Catalyzes the synthesis of phosphoribosylpyrophosphate (PRPP) that is essential for nucleotide synthesis.CATALYTIC ACTIVITY D-ribose 5-phosphate + ATP = 5-phospho-alpha-D-ribose 1-diphosphate + AMP + H(+)COFACTOR Activated by magnesium and inorganic phosphate.PATHWAY Metabolic intermediate biosynthesis; 5-phospho-alpha-D-ribose 1-diphosphate biosynthesis; 5-phospho-alpha-D-ribose 1-diphosphate from D-ribose 5-phosphate (route I): step 1/1.SUBUNIT Homodimer. The active form is probably a hexamer composed of 3 homodimers (By similarity).TISSUE SPECIFICITY Testis.SIMILARITY Belongs to the ribose-phosphate pyrophosphokinase family.CAUTION According to PubMed:2168892, this sequence initiates from a non-AUG codon; N-terminal ACG codon did serve as a start codon.
