Crystallization (Commentary)

Crystallization (Comment) Organism
hanging-drop vapor-diffusion method. Crystals of unliganded PhzF belong to space group P3(2)21 with a a = b = 56 A, and c = 156 A and hold one monomer per asymmetric unit. Complexes of PhzF (with 3-hydroxyanthranilic acid and trans-2,3-dihydro-3-hydroxyanthranilic acid) crystallize in space group P2(1)2(1)2 with cell parameters of a = 93 A, b = 100 A, and c = 57 A and contain one dimer in the asymmetric unit Pseudomonas fluorescens

(5S,6S)-6-amino-5-hydroxycyclohexane-1,3-diene-1-carboxyate charactierzation of the product by NMR spectrometry. The structure of PhzF in complex with its substrate, trans-2,3-dihydro-3-hydroxyanthranilic acid, suggests that it is an isomerase using the conserved glutamate45 to abstract a proton from C3 of the substrate. The proposed mechanism involves proton abstraction from C3 of trans-2,3-dihydro-3-hydroxyanthranilate by Glu45, followed by rearrangement of the double bonds and reprotonation at C1. The function of E45 as a proton shuttle is supported by results from NMR spectroscopy Pseudomonas fluorescens (1R,6S)-6-amino-5-oxocyclohex-2-ene-1-carboxylate

Subunits

Subunits Comment Organism
dimer deduced from crystal structure. The crystal structure clarifies that the enzyme is a dimer in an up/up configuration with the two active sites facing each other. The dimer in the open form, generates by crystal symmetry (sulfate complex), interacts mainly through the alpha1-helices and the beta16-strands in the N-terminal domains. The C-terminal domains are not in direct contact but are relatively close Pseudomonas fluorescens
