KEGG   ENZYME: 2.3.2.21
Entry
EC 2.3.2.21                 Enzyme                                 
Name
cyclo(L-tyrosyl-L-tyrosyl) synthase;
Rv2275 (gene name);
cYY synthase;
cyclodityrosine synthase
Class
Transferases;
Acyltransferases;
Aminoacyltransferases
Sysname
L-tyrosyl-tRNATyr:L-tyrosyl-tRNATyr tyrosyltransferase (cyclizing)
Reaction(IUBMB)
2 L-tyrosyl-tRNATyr = 2 tRNATyr + cyclo(L-tyrosyl-L-tyrosyl) [RN:R10335]
Reaction(KEGG)
R10335
Substrate
L-tyrosyl-tRNA(Tyr) [CPD:C02839]
Product
tRNA(Tyr) [CPD:C00787];
cyclo(L-tyrosyl-L-tyrosyl) [CPD:C20516]
Comment
The reaction proceeds following a ping-pong mechanism forming a covalent intermediate between an active site serine and the first L-tyrosine residue [2]. The protein, from the bacterium Mycobacterium tuberculosis, also forms small amounts of cyclo(L-tyrosyl-L-phenylalanyl) [1].
