FIG. 2.

Alignment of the amino acid sequences of the metC genes from L. lactis MG1363 (CBL-LLMG1363) and L. lactis B78 CBL-LLB78 with those of other members of the PLP-dependent protein family. Sequences were deduced from the following GenBank accession numbers: P56069 (Helicobacter pylori cystathionine γ-synthase [CGS-HPYL]), U93874 (B. subtilis cystathionine γ-lyase [CGL-BSUB]), Z99110 (B. subtilis CBL), P00935 (E. coli [ECOL] cystathionine γ-synthase), P06721 (E. coli CBL), and P44527 (Haemophilus influenzae [HIN] CBL). Conserved residues are indicated in white letters on a black background and with an asterisk underneath the sequences. The boxed region corresponds to a PLP binding site.
