Despite the paramount importance of protein-nucleic acid interactions in different cellular processes, our understanding of such interactions at the atomistic level remains incomplete. We have used molecular dynamics (MD) simulations and 15 μs of sampling time to study the behavior of amino acids and amino-acid sidechain analogs in aqueous solutions of different mimetics of naturally occurring ...

Xanthine (I) is converted to carbon dioxide, formic acid, glycine, and ammonia by crude extracts of Clostridium acidi-urici (1) and Clostridium cylindrosporum (2). Conditions under which an intermediate in this process is accumulated in incubation mixtures of xanthine and the crude extract were described in Paper III of this series (3). The compound was identified as 4-amino-5-imidazolecarboxyl...

Eksplan digunakan penelitian ini adalah bonggol pisang. Zat Pengatur Tumbuh yaitu Benzyl Amino Purine (BAP) Naphthalene Acetic Acid (N...

Pengaruh Konsentrasi 2,4-Dichlorophenoxyacetic Acid dan Benzyl Amino Purin terhadap Induksi Tunas Tanaman Nilam (Pogostemon cablin Benth.) Varietas Tapak Tuan secara In Vitro Abstrak. merupakan tumbuhan penghasil minyak atsiri potensial yang menyuplai 90 % kebutuhan nilam dunia. Faktor-faktor menyebabkan rendahnya produktivitas antara lain: mutu genetik tanaman, kurang tepatnya budidaya, pengen...

Treatment of 3-formylacetylacetone with the amines benzylamine, tert -butylamine and ( S )-methylbenzylamine led to formation corresponding Schiff bases 3-[(benzylamino)methylidene]pentane-2,4-dione, C 13 H 15 NO 2 1 ), 3-[( -butylamino)methylidene]pentan-2,4-dione, 10 17 ) 3-{[( )-benzyl(methyl)amino]methylidene}pentane-2,4-dione, 14 3 ). The molecules all three compounds exist as enamine taut...

New N-(benzyl carbamothioyl)-2-hydroxy substituted benzamides 13, 20, and 21 were synthesized using sodium bicarbonate and benzyl amine with 2-thioxo-substituted-1,3-benzoxazines 6, 10a, b, 11c, and 12a-n. The 2-thioxo-substituted-1,3-oxazines 6, 10a-b, 11d 12a-n, and 26 were converted to the corresponding 2-methylthio-substituted-1,3-oxazines 14a-l and 24 which were then converted to 2-benzyl ...

Somatic embryogenesis has been accomplished from tender leaf base explant of date palm (Phoenix dactylifera L.). Three to five mm long tender leaf base explants derived from the meristamatic region of 2-3 year old offshoots of date palm cv. Kheneizi were cultured on Murashige and Skoog (MS) basal medium supplemented with 10, 50, 100 and 150 mg l 2,4-dichlorophenoxy acetic acid (2,4-D) and incub...

This study was conducted to evaluate the effect of plant growth regulators on in vitro shoot multiplication, vitrification and rooting of two carnation cultivars (Eskimo Mogr and Innove Orange Bogr). Isolated axillary buds were cultured on MS medium supplemented with different levels of Benzyl amino purine (BAP) or kinetin (Kin) in combination with 0.2 mg/l NAA and shoot multiplication and vitr...

A simple and efficient protocol for in vitro shoot and callus induction was established from three different explants of Canavalia gladiata (Jacq.) DC. an economically important legume. The explants viz., shoot buds, nodes, internodes were cultured in MS medium supplemented with various concentration and combination of (PGRs) Plant growth regulators 6-benzyl amino purine (BAP) (0.5mg/L – 1.5mg/...
