ADCY10 and infection: Herein, we investigate the role of a BglG/SacY antiterminator homolog as a link between the metabolism and the opportunistic features of E. faecalis. An interesting aspect is that the β-glucosides metabolism was shown to be induced during infection (Muller et al., 2015), so we studied the regulation of this metabolism in E. faecalis by the ef1515-ef1516 operon encoding a BglG/SacY-like antiterminator (NagY) and a NAG PTS transporter (NagE; Keffeler et al., 2021b).
