Alignment of the amino acid sequence of Lactobacillus futsaii CS3 GadB (LfuCS3) with GadB proteins from other LAB (LpWCFS1, Lactobacillus plantarum WCFS1; LpJDM1, Lactobacillus plantarum JDM1; LbCGMCC1306, Lactobacillus brevis CGMCC1306; LrATCC23272, Lactobacillus reuteri ATCC23272; LdATCC11842, Lactobacillus delbrueckii subsp. bulgaricus ATCC11842; LcATCC11454, Lactococcus lactis subsp. lactis ATCC11454; LfYS2, Lactobacillus fermentum YS2). The amino acid residues (HVDAASGG) marked by a box are highly conserved in pyridoxal 5′-phosphate-dependent decarboxylases; the amino acid residues in the second box represent the pyridoxal 5′-phosphate binding domain
