[[3rit]] is a 5 chain structure of [[Muconate cycloisomerase]] with sequence from [http://en.wikipedia.org/wiki/Methylococcus_capsulatus Methylococcus capsulatus]. Full crystallographic information is available from [http://oca.weizmann.ac.il/oca-bin/ocashort?id=3RIT OCA].

== Function ==
[https://www.uniprot.org/uniprot/KRDE_METCA KRDE_METCA] Catalyzes the epimerization of L-Lys-L-Arg to L-Lys-D-Arg. Can also catalyze the epimerization of other cationic dipeptides, such as L-Arg-L-Arg, L-Lys-L-Lys and L-Lys-L-His, but with lower efficiency (in vitro).<ref>PMID:22392983</ref>
