process for the removal of the groups protecting the thiol groups present in the amino - acids and peptides. Remove the protective groups protecting the thiol groups of an amino - acid or a peptide, a thiol groups protected by the groups methoxybenzyl para -, - adamantyl or tertio - butyl...
[C 1-5 alkylamino], N-carbobenzyloxy-C 1-5 alkyl) amino, or an OZ radical where Z is a cation, R 1 , R 3 and R 3 signify H, C 1-5 alkyl or phenyl, each of R 4 and R 5 is H, C 1-5 alkyl, C 1-6 alkanoyl or phenyl or R 4 is guanyl and R 5 is H, and R ...
Cloning and characterization of glyceraldehyde-3-phosphate dehydrogenase gene from Chaetomium globosum球毛壳菌甘油醛-3-磷酸脱氢酶基因克隆及特性分析 The amino acid sequence of Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) gene from Neurospora crassa (XP-327967) and Colletotrichum lindemuthianu (P3514.....
24). Collectively, these results demonstrated the polymer composition, namely the amount of hydrophobic styrene residues and the number and positioning of the phenolic groups, plays an important role in underwater adhesion. The comparison between P(2HS-co-S) and P(5HS-co-S) with similar total...
Independent claims are also included for: (1) a sulfonic-acid-group and/or mercapto group containing layer silicate with a sulfur content, related to silicon dioxide of layer silicate of 0.02-1000 (preferably 1-200) mmol, related to 100 g of layer silicate (mmol/100 g); (2) an ...
abovementioned inert solvents at or about ambient room temperature in the presence of dicyclohexylcarbodiimide or carbonyl bis-imidazole, or the like; or by activating the acid portion of the amino acid as by the formation of an acid chloride, acid anhydride, or mixed anhydride, or the like. ...
An amino acid bearing an unprotected ketone group, (2 S )-aminolevulinic acid, was incorporated into a synthetic peptide using standard Fmoc-based solid-phase methods. The ketone group remained unharmed during the synthesis and provided a uniquely reactive functional group for covalent modification of...
hydroxylases enables the hydroxylation of an amino acid at a certain carbon position can be realized by selecting or designing a proper hydroxylase, offering thereby the possibility to generate structurally diverse diols from the same amino acid (Fig.1c)13,14. Last but not least, relatively ...
IT was shown by Albert and Goldacrethat an amino group substituted in a `resonant position' of a six-membered aromatic heterocyclic base results in a compound of enhanced basic strength. This is attributed to the replacement of a dipolar resonant form by a more stable homopolar resonant form.DO...
