L-leucyl-tRNALeu:L-leucyl-tRNALeu leucyltransferase (cyclizing)
The reaction proceeds following a ping-pong mechanism forming a covalent intermediate between an active site serine and the first L-leucine residue [2]. The proteins from bacteria of the genus Bacillus also form small amounts of cyclo(L-phenylalanyl-L-leucyl) and cyclo(L-leucyl-L-methionyl) [1].
