Functional analysis reveals oligopeptides aid nitrogen acquisition in Lacticaseibacillus paracasei, suggesting avenues for probiotics in dairy.
Graphical abstract Lacticaseibacillus paracasei strain Shirota (LcS) employs two distinct oligopeptide transporters, Opp Lc and Dpp Lc , to facilitate nitrogen acquisition during growth in milk. These transporters exhibit differential substrate specificity, enabling the uptake of oligopeptides of varying lengths derived from milk proteins.
