The human RKIP protein is composed of 187 amino acids which gives rise to the 23-kDa protein. The amino acid sequence is listed in Table 1. The protein contains two main structures: a hydrophobic cavity that serves as the ligand-binding pocket, and a globular structure for its interactions ...
resulting in the transfer of methyl groups from AdoMet onto lysine residues of particular substrates. Subsequently, AdoMet is converted to S-adenosyl-L-homocysteine (AdoHcy), the demethylated form of AdoMet. The lysine ε-amino acid groups can receive up to three methyl groups,...
Oxidative damage can have a devastating effect on the structure and activity of proteins, and may even lead to cell death. The sulfur-containing amino acids cysteine and methionine are particularly susceptible to reactive oxygen species (ROS) and reactive chlorine species (RCS), which can damage ...
Dietary proteins have been used for years to treat obesity. Body weight loss is beneficial when it concerns fat mass, but loss of fat free mass – esp
Fats in foods are not composed of a single type or category of fatty acids, rather each dietary fat is a complex mixture of different fatty acids (Wardlaw and Kessel, 2002; Enwere, 1998). It has been reported that the total lipid content of plant foods varies with variety, ...
In this paper, we have developed an efficient and fast technique for predicting protein interactions from protein amino acids sequences by combining ensemble ELM with PCA. The main aim of the proposed method is to employ the unique features of ELM classifier including better generalization performance...
Enzymatic elaboration of proteinogenicamino acidsis the most common pathway to nonproteinogenic amino acids. Six representative examples are illustrated inFigure 14(b). Amino acids that have undergoneoxidationat the β-position are frequently incorporated in NRPs. Thebiosynthesisof β-hydroxyhistidine fro...
Protein synthesisRibosomes are key components of protein synthesis in cells. The common property of all proteins is that they consist of long chains ofα-amino (alpha amino) acids. The α-amino acids are so called because the α-carbonatomin themoleculecarries an amino group (―NH2); the ...
Tryptophan, an amino acid that is nutritionally important and occurs in small amounts in proteins. It is an essential amino acid, meaning that humans and certain other animals cannot synthesize it and must obtain it from their diets. Infants require grea
