Identification and molecular characterization of a metagenome-derived L-lysine decarboxylase gene from subtropical soil microorganisms
Fig 1
Multiple sequence alignment of the Ldc1E protein and other LDCs.
Colored boxes indicate the secondary structures, which were predicted by PSIPRED Server, with helix and sheets represented by red and yellow boxes, respectively. Dashes indicate gaps. Conserved LDC decarboxylase motifs are indicated in the blue line. Red and blue asterisks show the conserved residues in PLP binding sites and the predicted residues in L-lysine binding sites, respectively. The sequences from top to bottom are E. coli K-12 LDC (P52095.2), E. coli O157:H7 LDC (P0A9H4.1), S. enterica subsp. LT2 LDC (P0A1Z0.1), H. alvei LDC (P05033.1) and A. hydrophila AL06-06 (WP_017408594.1).
