The iol operon. The iol genes are labeled based on the homology/conserved motif of their encoded proteins with known enzymes necessary for myo-inositol degradation. For all strains, the described or probable regulator is represented in blue. E. faecalis OG1RF: the iol operon is represented in yellow, OG1RF_0166 (green arrow) located downstream of the iol operon encodes a probable PTS IIC component, while the white arrows indicate ORFs also present in V583. For B. subtilis 168, C. perfringens strain 13, and L. casei BL23, the iol genes are represented in green, orange and purple, respectively. C. perfringens iol mRNA transcript includes five other genes encoding proteins whose functions do not appear to be related to myo-inositol degradation; these genes are represented in gray.
