FIG 1.
Schematic diagrams of MARTXVv toxins from representative clinical biotype 1 V. vulnificus strains (indicated on the left) showing distinct arrangements of effector domains. Effector domains are designated domain of unknown function in the first position (DUF1), Rho inactivation domain (RID), alpha-beta hydrolase (ABH), Makes Caterpillars Floppy-like (MCF), Ras/Rap1-specific protease (RRSP), and the cysteine protease domain (CPD). Note that MCF (gray) is the only domain present in all variants. The arrangements here are based on sequencing found in the work of Kwak et al. (21).
