2.A.1.2.51
Chloramphenicol resistance pump, CraA (43% identical to MdfA of E. coli) (Roca et al., 2009). It is a broad specificity transporter exporting chloramphenicol, thiamphenicol, florfenicol, ethidium, dequalinium, chlorhexidine, benzalkonium, mitomycin C and TPP+. Glu-38 is essential for activity (Foong et al. 2019).
