abstract：:Acyl carrier protein (ACP) is a small acidic protein that acts as an essential cofactor in many biosynthetic pathways depending on acyl transfer reactions. In this work, a Vibrio anguillarum ACP encoding gene, acpV, was first cloned from the chromosome of a virulent V. anguillarum strain MVM425. acpV was over-expresse...
