PUMPK_ARATH | function | Catalyzes the reversible phosphorylation of UMP to UDP (PubMed:30409856). Required for specific post-transcriptional processes of many plastid transcripts (e.g. PSI (PsaA, PsaF), PSII (D1, CP43, CP47), Cytochrome b(6)f (Cytb(6)), ATP synthase (AtpC), LHCs (LHCa3, LHCb2), and NDH (NdhH)), thus being essential for retaining photosynthetic activity in chloroplasts (PubMed:19037728, PubMed:30409856). Associates with group II introns of the plastid transcripts trnG-UCC, trnV-UAC, petB, petD and ndhA to stabilize corresponding precursor RNAs (PubMed:30409856). |
A0A1I9LRT3_ARATH PUMPK_ARATH | pathway | Pyrimidine metabolism; CTP biosynthesis via de novo pathway; UDP from UMP (UMPK route): step 1/1. |
A0A1I9LRT3_ARATH PUMPK_ARATH | similarity | Belongs to the UMP kinase family. |
PUMPK_ARATH | tissue specificity | Expressed exclusively in leaves, but not in roots. |
