Potential applications of recombinant bifidobacterial proteins in the food industry, biomedicine, process innovation and glycobiology.

ABSTRACT: Bifidobacterial proteins have been widely studied to elucidate the metabolic mechanisms of diet adaptation and survival of Bifidobacteria, among others. The use of heterologous expression systems to obtain proteins in sufficient quantities to be characterized has been essential in these studies. L. lactis and the same Bifidobacterium as expression systems highlight ways to corroborate some of the functions attributed to these proteins. The most studied proteins are enzymes related to carbohydrate metabolism, particularly glycosidases, due to their potential application in the synthesis of neoglycoconjugates, prebiotic neooligosaccharides, and active metabolites as well as their high specificity and efficiency in processing glycoconjugates. In this review, we classified the recombinant bifidobacterial proteins reported to date whose characterization has demonstrated their usefulness or their ability to produce a product of commercial interest for the food industry, biomedicine, process innovation and glycobiology. Future directions for their study are also discussed.
