ENTRY       EC 2.8.1.4
NAME        tRNA sulfurtransferase
CLASS       Transferases
            Transferring sulfur-containing groups
            Sulfurtransferases
SYSNAME     L-Cysteine:tRNA sulfurtransferase
REACTION    L-Cysteine + 'Activated' tRNA = L-Serine +
            tRNA containing a thionucleotide
SUBSTRATE   L-Cysteine
            'Activated' tRNA
PRODUCT     L-Serine
            tRNA containing a thionucleotide
COMMENT     A group of enzymes transferring sulfur to various nucleotides in
            a tRNA chain, producing residues such as 4-thiouridylate. Wite
            some enzymes mercaptopyruvate can act as sulfur donor.
