Zobellia galactanivorans is a gram-negative marine bacterium isolated from the surface of red algae of the coast of France . Z. galactanivorans forms yellow colonies with a bacillus or diplobacillus morphology. Furthermore, it is mesophilic and can grow degrade carrageenans and agars - both found in the cell wall of red algae.[1] Z. galactanivorans contains the gene porA and porB, each encoding a β-porphyranase.[2]
β-porphyranase
porA and porB are catalytic enzymes that hydrolyze the β-D-galactopyranose (1→4) α-L-galactopyranose-6-sulfate linkage in porphyran.[3] There is a 35% sequence similarity between β-Porphyranase-B and β-Porphyranase-A. [3]
Horizontal gene transfer
Orthologs between Z. galactanivorans and Bacteroides plebeius-1698, a strain of Bacteroides plebeius, contain a sequence similarity of 48%-69%.[3] Homologous genes between other Bacteroides species only have a 30% sequence similarity.[3] Moreover, porphyranase genes in both Z. galactanivorans and B. plebeius are located in similar orders along their chromosome, or are syntenic.
