Solution structure of MerB, the Organomercurial Lyase involved in the bacterial mercury resistance system

The structure was published by Di Lello, P., Benison, G.C., Valafar, H., et al., Summers, A.O., Legault, P., and Omichinski, J.G., in 2004 in a paper entitled "NMR structural studies reveal a novel protein fold for MerB, the organomercurial lyase involved in the bacterial mercury resistance system." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2004.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of Alkylmercury lyase. This molecule has the UniProt identifier P77072 (MERB_ECOLX)search. The sample contained 212 residues which is 100% of the natural sequence. Out of 212 residues 192 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
