Among the important functions predicted for OGG1 proteins were LIG_BRCT_BRCA1_1 instances of Phosphopeptide motif which directly interacts with the BRCT (carboxy-terminal) domain of the breast cancer gene BRCA1, LIG_FHA_2 of Phosphothreonine motif binding a subset of FHA domains that have a preference for an acidic amino acid at the replication fork, and MOD_TYR_ITSM of the CD150 subfamily of receptors that bind to and are regulated by SH2 adaptor molecule.
The percentage of total neutral amino acid (TNAA) ranged from 54.9-56.3, indicating that they formed the bulk of the amino acids; total acidic amino acid (TAAA) ranged from 27.2-27.4% which were far lower than % TNAA, whilst the percentage range in total basic amino acid (TBAA) was 15.6-17.9, which made them the third largest group among the samples.
By studying all genotypes P7 fragment of E2, we found its specific characters: there are many prolines in P7 fragment (15%~20%), making the peptide unique tertiary structure; the basic amino acid could strengthen the affinity with ZE2 while acidic amino acid could weaken this combination.

As indicated, an acidic amino acid is one that contains within its residue a carboxylic acid group symbolized by--C(O)OH (see Chart 5).
A substitution at residue 156(G156E) shows a neutral to acidic amino acid change similar to those observed in some other Beijing/262-like viruses.
According to the present invention, a cDNA can be obtained encoding the amino acid sequence of aminopeptidase GX suitable for producing a highly hydrolized product from a starting material containing a protein and peptide having a high acidic amino acid content.
Under physiologic conditions, large amounts of EAAS are stored in intracellular compartments; the EAA concentrations in the cytoplasm of brain cell are conspicuously higher than those in the extracellular space, a gradient maintained by acidic amino acid carriers present in both presynaptic and glial plasma membranes.
Comparison of amino acid sequences of chondroitin sulfate attachment sites in different proteoglycans (Table 1) led to a consensus sequence--a-a-a-x-S-G-x-G--with at least one acidic amino acid "a" and variable amino acids "x".
found that the accuracy and CVs were highly variable across the different analytes, in a way that basic amino acids (CV 6.4-18.1%) and acidic amino acids (CV 7-13.7%) demonstrated higher CVs when compared with neutral amino acids (CV 3.3-5%) [15].
It has 17 strong basic amino acids, 14 strongly acidic amino acids, 52 hydrophobic amino acids and 43 polar amino acids.
The colour intensity of MRP from basic amino acids was reportedly greater than that of acidic amino acids, while nonpolar amino acids were of intermediate colour intensity.
