The ratio gives the relative hydrophobicity scale for individual amino acids. Computation was trained on high resolution protein crystal structures. This quantitative descriptor for microenvironment was derived from the octanol-water partition coefficient , (known as Rekker's Fragmental Constants) widely used for pharmacophores.
Amino acid replacement is a change from one amino acid to a different amino acid in a protein due to point mutation in the corresponding DNA sequence. It is caused by nonsynonymous missense mutation which changes the codon sequence to code other amino acid instead of the original.
The foodstuffs listed for comparison show the essential amino acid content per unit of the total protein of the food, 100g of spinach, for example, only contains 2.9g of protein (6% Daily Value), and of that protein 1.36% is tryptophan.

The clamp-polymerase protein–protein interactions are stronger and more specific than the direct interactions between the polymerase and the template DNA strand; because one of the rate-limiting steps in the DNA synthesis reaction is the association of the polymerase with the DNA template, the presence of the sliding clamp dramatically ...
Gwen's boyfriend, Richard "Dick" Bagg, is a pre-med student and the president of his fraternity Delta Iota Kappa, as well as of the student government. As he learns of Gwen's work with Van, suspecting a growing bond between them, he moves to sabotage their prospective romance. Van and Richard exchange escalating pranks.
It enters the problem of estimating the mean of a normally distributed population and the problem of estimating the slope of a regression line via its role in Student's t-distribution. It enters all analysis of variance problems via its role in the F-distribution , which is the distribution of the ratio of two independent chi-squared random ...
The modern anamorphic format has an aspect ratio of 2.39:1, meaning the (projected) picture's width is 2.39 times its height, (this is sometimes approximated to 2.4:1). The older Academy format of Anamorphic widescreen was a response to a shortcoming in the non-anamorphic spherical (a.k.a. "flat") widescreen format.
The M protein is the viral protein responsible for the transmembrane transport of nutrients. It is the cause of the bud release and the formation of the viral envelope. [ 163 ] The N and E protein are accessory proteins that interfere with the host's immune response.
