Dual functions of a 4-hydroxyphenylpyruvate dioxygenase for Vibrio splendidus survival and infection

Vibrio splendidus is a well-documented pathogenic bacterium that can trigger different diseases, including skin ulcer syndrome in Apostichopus japonicus. In our previous study, a gene named Vshppd encoding a 4-hydroxyphenylpyruvate dioxygenase homologue was cloned from pathogenic V. splendidus, and validated to be responsible for the haemolysis activities of V. splendidus. In this study, Vshppd was determined to participate in the catabolism of...
