The general control of amino acid was investigated in henricii. By limitation for single amino acids in wild type strain and mutants no derepression of enzymes was caused. In prototrophic revertants however, obtained from auxotrophic mutants (his, pdx) were 2 - 17 times higher than in the wil...
Since the structure and function of proteins are determined by the kinds of amino acids used to make it and how they are arranged, how come the amino acid sequence of PrP^C and PrP^{Sc} are the same, when they have very different func...
[Cell 59 (1989) 219-228] significant amino acid (aa) sequence similarity has been found in the C-terminal portion of 27 DNA-dependent belonging to the two main superfamilies: (i) ()-like prokaryotic , and (ii) alpha-like prokaryotic and eukaryotic (viral and cellular) . The six most ...
Synthesis and structural analysis of titanium-μ-dinitrogen complex supported by di-anionic guanidinate ligands Botao Wu, Rui Feng, Zhu-Bao Yin, Haihan Yan, Xueli Wang, Gao-Xiang Wang, Junnian Wei & Zhenfeng Xi Sci. Ch...
Cysteine proteases of positive strand RNA viruses and chymotrypsin-like serine proteases. A distinct protein superfamily with a common structural fold. Evidence is presented, based on sequence comparison and secondary structure prediction, of structural and evolutionary relationship between chymotrypsin-li.....
Structure prediction of HPFlongby the Predict Protein Server23(Supplementary Fig.9) revealed a two-domain architecture connected through an unstructured, solvent-exposed linker. The HPFlongN-terminal domain (residues 1-102, Fig.2b), located between the 30 and 50S subunits, is in close proximity ...
To the end user, the algorithm requires only a single wild-type sequence, without any initial binding affinity data, knowledge of the antigen, task-specific supervision, evolutionary homologs or protein structure information. We evolved seven human immunoglobulin G (IgG) antibodies that bind to ...
This four-point enclosure can be constructed around every hydrophobic amino acid in the a/a’ and d/d’ positions; this arrangement is often referred to as a “knobs-in-holes” structure. In dimers, the amino acids at e and g form ionic bonds that determine the specificity of dimeriza...
Intrinsic amino acid size parametersPeptide ion structureA database of 1470 collision cross sections (666 doubly- and 804 triply-charged) of alkaline-earth-coordinated tryptic peptide ions [where the cation (M) correspond to Mg, Ca, or Ba] is presented. The utility of such an extensive set ...
