MJ0757

Gene
MJ0757
Protein
Thymidylate synthase
Organism
Methanocaldococcus jannaschii (strain ATCC 43067 / DSM 2661 / JAL-1 / JCM 10045 / NBRC 100440)
Length
260 amino acids
Function
Is able to catalyze the biosynthesis of dTMP using dUMP, tetrahydrofolate and formaldehyde in vitro, i.e. a reaction equivalent to that catalyzed by bacterial thymidylate synthases (EC 2.1.1.45). However, M.jannaschii like most methanogenic Archaea lacks folates, thus the physiological cosubstrate is unknown but is likely one of the non-methylated methanopterin biosynthetic intermediates.
