Lethal attribute of serine protease secreted by Vibrio alginolyticus strains in kuruma prawn Penaeus japonicus.
Toxicity of the extracellular products (ECP) and the lethal attribute of serine protease secreted by five pathogenic Vibrio alginolyticus strains from various sources in kuruma prawn Penaeus japonicus were studied. The ECPs of organisms originally isolated from diseased kuruma prawn or small abalone Haliotis diversicolor supertexta were more lethal (LD50 value of 0.48 or 0.41 microg protein/g p...
متن کاملAnti-lipopolysaccharide factor evokes indirect killing of virulent bacteria in kuruma prawn.
AIMS Anti-lipopolysaccharide factor (ALF) is an antimicrobial peptide (AMP) and a key effector molecule of the innate immune system in crustaceans. However, little is known about the role of its indirect killing against bacteria. The possible regulatory role of this peptide (M-ALF) in kuruma prawns, Marsupenaeus japonicus, was investigated. MATERIALS AND METHODS The activities of M-ALF were i...
متن کاملThe solution structure of molt-inhibiting hormone from the Kuruma prawn Marsupenaeus japonicus.
Molting in crustaceans is controlled by molt-inhibiting hormone (MIH) and ecdysteroids. It is presumed that MIH inhibits the synthesis and the secretion of ecdysteroids by the Y-organ, resulting in molt suppression. The amino acid sequence of MIH is similar to that of crustacean hyperglycemic hormone (CHH), and therefore, they form a peptide family referred to as the CHH family. Most of the CHH...
متن کاملExpression and Purification of Active Recombinant Cathepsin C (Dipeptidyl Aminopeptidase I) of Kuruma Prawn Marsupenaeus japonicus in Insect Cells
Cathepsin C (CTSC) is a lysosomal cysteine protease belonging to the papain superfamily. Our previous study showed that CTSC precursor (zymogen) is localized exclusively in cortical rods (CRs) of mature oocyte in the kuruma prawn Marsupenaeus japonicus, suggesting that CTSC might have roles on regulating release and/or formation of a jelly layer. In this study, enzymically active CTSC of the ku...
متن کاملSynchronous gamete maturation and reliable spawning induction method in holothurians
Several years of research on the gametic development and spawning of different species of holothurians have produced results that find applications in aquaculture and fisheries management programs. The first set of data shows that sea cucumbers secrete a biologically active chemical which allows gamete synthesis synchrony among conspecifics. Laboratory experiments have revealed that the gametic...
