چکیده

Renin is the rate limiting enzyme in the renin-angiotensin (RA) system that regulates blood pressure and electrolyte balance. In this study, we investigated the renin inhibitory effect of a royal jelly (RJ)-derived peptide. A dipeptide YY was isolated from the digested fraction of RJ proteins by proteases and was found to inhibit human renin activity. The inhibition constant (Ki) of YY was estimated to be 10 microM when the Km was 0.16 microM using sheep angiotensinogen as the substrate. The peptide was observed to lower blood pressure in spontaneously hypertensive rats.

A peptide YY inhibits the human renin activity in a pH dependent manner.

Royal jelly (RJ) is known to possess several physiological and pharmacological properties. A dipeptide YY derived from RJ proteins is known to inhibit angiotensin converting enzyme (ACE) activity. Our previous study showed that the dipeptide YY inhibited the human renin activity at physiological pH. In this study, we investigated the pH dependency of the inhibitory effect of the dipeptide YY to...

A Survy on Deletion and Insertions Presented in MRJP3 (Major Royal Jelly Protein 3) Gene in Isfahan Persian Hony Bee (Apis Mellifera Meda)

Objectives: Royal jelly (RJ), a secretion of both the hypopharyngeal and mandibular glands of nurse workers, is believed to play a central role in honeybee queen development. Important component of royal jelly are proteins which form about 50% of the dry mass of RJ. Major royal jelly proteins (MRJPs) are the dominant proteinaceous component of royal jelly and constitute about 82-90% of total pr...
