Abstract

Recombinant peptides related to vitellogenesis-inhibiting hormone (VIH) of the American lobster Homarus americanus were expressed in bacterial cells, and then purified after being allowed to refold. Biological activities of the recombinant VIHs having an amidated C-terminus (rHoa-VIH-amide) and a free carboxyl-terminus (rHoa-VIH-OH) were examined using an ovarian fragment incubation system derived from the kuruma prawn, Marsupenaeus japonicus. The rHoa-VIH-amide significantly reduced vitellogenin mRNA levels in the ovary, while rHoa-VIH-OH had no effect. This is the first report that describes the production of a crustacean VIH having biological activity and the importance of the C-terminal amidation for its vitellogenesis-inhibiting activity.
