Abstract

The promoter region of alginate lyase gene (aly) from Pseudomonas sp. W7 was used for the high expression of gilthead seabream (Sparus aurata) growth hormone (GH) gene in Esherichia coli. PCR product encoding the premature segment of the growth hormone. was cloned to the downstream of aly promoter. GH was overexpressed With 46 ammo acid of alginate lyase as fusion protein. GH was immunoreactive and production of GH was repressed with supplementation of $0.4\%$ glucose into culture media.
