CYSTATHIONINE BETA-LYASE (CBL) FROM ESCHERICHIA COLI
Overview
Cystathionine beta-lyase (CBL) is a member of the gamma-family of, PLP-dependent enzymes, that cleaves C beta-S bonds of a broad variety of, substrates. The crystal structure of CBL from E. coli has been solved, using MIR phases in combination with density modification. The structure, has been refined to an R-factor of 15.2% at 1.83 A resolution using, synchroton radiation diffraction data. The asymmetric unit of the crystal, cell (space group C222(1)) contains two monomers related by 2-fold, symmetry. A homotetramer with 222 symmetry is built up by crystallographic, and non-crystallographic symmetry. Each monomer of CBL can be described in, terms of three spatially and functionally different domains. The, N-terminal domain (residues 1 to 60) consists of three alpha-helices and, one ...
