LITERATURE
to 1.7 A resolution with cinnamate included in the crystallization buffer. The monomer consists of mostly alphahelices that run parallel to one another and form a four-helix bundle at the center. The catalytically relevant species is a dimer of dimers, in which the two monomers in the asymmetric unit are related by a crystallographic twofold axis to the other two monomers that comprise the catalytically functional tetramer, and each subunit contains an active site. During the reaction, the phenylpropanoid carbon backbone remains mostly stationary above the amino group that is attached to the cofactor moiety
