Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (TRMFO_THET8 | Q5SID2)
molecular function
    GO:0030698    5,10-methylenetetrahydrofolate-dependent tRNA (m5U54) methyltransferase activity    Catalysis of the transfer of a methyl group from 5,10-methylenetetrahydrofolate to the C5 atom of the uridine residue at position 54 in a tRNA molecule. This occurs in most Gram-positive bacteria and some Gram-negative bacteria.
    GO:0050660    flavin adenine dinucleotide binding    Interacting selectively and non-covalently with FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes, in either the oxidized form, FAD, or the reduced form, FADH2.
    GO:0047151    methylenetetrahydrofolate-tRNA-(uracil-5-)-methyltransferase (FADH2-oxidizing) activity    Catalysis of the reaction: 5,10-methylenetetrahydrofolate + tRNA containing uridine at position 54 + FADH + H+ = tetrahydrofolate + tRNA containing ribothymidine at position 54 + FAD+.
    GO:0008168    methyltransferase activity    Catalysis of the transfer of a methyl group to an acceptor molecule.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
    GO:0008033    tRNA processing    The process in which a pre-tRNA molecule is converted to a mature tRNA, ready for addition of an aminoacyl group.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
