Diversity of enzymes for exopolysaccharide synthesis in the fructophilic honeybee symbiont Apilactobacillus kunkeei.

ABSTRACT:

Background

Apilactobacillus kunkeei is a fructophilic lactic acid bacterium adapted to honeybees, their food sources and products. These bacteria synthesize exopolysaccharides thought to promote host colonization and protection against toxic compounds and stressful conditions. Homopolysaccharides consisting of glucose residues are synthesized by enzymes in the glycoside hydrolase family 70 (GH70), whereas polysaccharides that contain fructose are synthesized by family 32 (GH32) enzymes. However, the mechanisms whereby these enzymes diversify are not well understood. Here, we used a comparative genomics approach to investigate the evolution of GH70 and GH32 enzymes in the A. kunkeei population.

Results

Based on phylogenetic inferences, the GH70 proteins in 38 reference A. kun
