The position of the site of phosphorylation (serine 133 in CREB and serine 276 in p65) at opposite ends in the region of homology suggests that recognition of the phosphorylated proteins by CBP-KIX involves that domain of the protein rather than just the phosphorylated amino acid. It also ...
Every amino acid comes in two forms, a 'left-handed' (L) and a 'right-handed' (D) form. These two forms are identical in every respect except for the conformation of the subunits of which they are composed. That is to say, although chemically they contain the same elements, in precis...
5.3.3Smart behavior of alginates The pKavalues for –COOH groups in M and G are 3.38 and 3.65, respectively. This results in precipitation of the soluble polymer below pH 2. However, most of the applications of alginate arise from the fact that it forms insoluble gels/precipitates withdivale...
For example, the pK_a of the -NH_3^+ group of alanine is 9.87 but the pK_a of CH_3NH_3^+ is 10.63. Two pKa values are reported for malonic acid, a compound with two COOH groups. Explain why...
