UPM1_ARATH | function | Essential protein required for siroheme biosynthesis (PubMed:20592802). Catalyzes the two successive C-2 and C-7 methylation reactions involved in the conversion of uroporphyrinogen III to precorrin-2 via the intermediate formation of precorrin-1 (PubMed:9006913). It is a step in the biosynthesis of siroheme (PubMed:9006913). Promotes nitrogen and sulfur assimilation as well as photosynthesis efficiency by triggering chlorophyll, nitrite reductase (NiR) and sulfite reductase (SiR) biosynthesis (PubMed:29472934). |
UPM1_ARATH | pathway | Porphyrin-containing compound metabolism; siroheme biosynthesis; precorrin-2 from uroporphyrinogen III: step 1/1. |
F4KIS7_ARATH UPM1_ARATH A0A1P8BE13_ARATH | similarity | Belongs to the precorrin methyltransferase family. |
UPM1_ARATH | tissue specificity | Mostly expressed in leaves, and, to a lower extent, in stems, flowers and siliques. |
