momordin/momordica

OBJECTIVE Bitter melon (Momordica charantia L.) is a common vegetable grown in Okinawa that has also been used recently in medicine for the treatment of diseases such as diabetes, hypertension, and dyslipidemia. Among Bitter melon extracts compounds, we focused on an extract known as momordin in the

Effects of chemical modifications on the protein-synthesis inhibitory (PSI) activities of momordin-a and luffin-a were investigated. Treatment with a 50-fold excess of diethylpyrocarbonate at pH 6.5 modified one histidine residue in momordin-a and luffin-a and reduced their PSI activities to 10% and

The complete amino acid sequence of momordin-a, a ribosome-inactivating protein from the seeds of bitter gourd, has been analyzed. Twenty-two peptides were isolated from the tryptic digest of momordin-a and sequenced by the DABITC/PITC double coupling method. The alignment of these tryptic peptides

The structures of the N-linked oligosaccharides of momordin-a, which is a ribosome-inactivating protein from the seeds of Momordica charantia, were analyzed. First, the N-linked oligosaccharides of this glycoprotein were liberated by hydrazinolysis. After N-acetylation, the reducing ends of the

A type I ribosome-inactivating protein, extracted and purified from M. charantia seeds, was crystallised by vapour diffusion with polyethylene glycol at pH 7.2. X-ray data were collected to 2.1 A resolution and the structure solved by molecular replacement using the A-chain coordinates of ricin. The

Three isolectins denoted hereforth MBaL-30, MBaL-60, and MBaL-80 were isolated from seeds extract of Momordica balsamina by 30%, 60%, and 80% ammonium sulfate saturations, respectively. The native molecular weights of these lectins, as judged by gel filtration, were 108, 56, and 160 kDa,

This research isolated two new oleanane-type triterpene glycosides, named mocochinosides A (1) and B (2), together with ten known compounds as chikusetsusaponin IVa ethyl ester (3), momordin Ib (4), momordin IIb (5), momordin II (6), calenduloside G

Momordica balsamina, African pumpkin (Cucurbitaceae), is a tendril-bearing, wild climber containing wide spectrum of medicinal and nutritional values and has been used as a traditional folk medicine in many countries. The leaves, fruits, seeds, and bark of the plant contains resins, alkaloids,

The interaction of momordin, a type 1 ribosome-inactivating protein from Momordica charantia, with NADP(+) and NADPH has been investigated by X-ray diffraction analysis of complexes generated by co-crystallization and crystal soaking. It is known that the proteins of this family readily cleave the

Momordica charantia (Family: Cucurbitales), as known as bitter melon or gourd, is a daily consumption as food and traditional medicinal plant in Southeast Asia and Indo-China. It has been shown to possess anticancer, antidepressant, antidiabetic, anti-inflammatory, antimicrobial, antiobesity,
