This modelled transmembrane complex provides a structural explanation for the uncoupling of haem biosynthesis observed in variegate porphyria patients and in plants after inhibiting PPO.

The crystal structure of cystathionine γ-lyase (CGL) from yeast has been solved by molecular replacement at a resolution of 2.6 å and a structure comparison with other family members revealed surprising insights into the tuning of enzymatic specificity between the different family members.

The relationships suggest that laccase, like ascorbate oxidase, has a mononuclear blue copper in domain 3 and a trinuclear copper between domain 1 and 3 and ceruloplasmin has mon onuclear copper ions in domains 2, 4 and 6 and atrinuclear Copper between domains 1 and 6.

By comparing the haem arrangement of this nitrite reductase with that of other multihaem cytochromes, this work has been able to identify a family of proteins in which the orientation of haem groups is conserved whereas structure and function are not.

The crystal structure of CBL from E. coli has been solved using MIR phases in combination with density modification and suggests that Lys210, the PLP-binding residue, mediates the proton transfer between C alpha and S gamma.

- 2 October 2002
A working hypothesis for the reaction mechanism of this multiheme enzyme which carries a novel lysine-coordinated heme group (Fe-Lys) is presented and it is proposed that nitrite reduction starts with a heterolytic cleavage of the N-O bond.
