Motifs are simple combinations of secondary structure that occur in many different proteins and which carry out a similar function. An example is the helix-loop helix. It consists of two antiparallel helices at about a 60-degree angle to each other connected by a loop. This motif, which binds...
Core structure:is very similar in different types of ribosomes, although noticeably large differences exist in size. Ribosomal RNA organization:in tertiary structural motifs. The catalytic activity of the ribosomes:Carried out by the ribosomal RNA (rRNA). ...
The helix-turn-helix motif from the CAP family of homodimeric DNA binding proteins. CAP (Catabolite Activator Protein, also known as CRP for cAMP Receptor Protein) is a transcription promoter that binds at more than 100 sites within theE. coligenome. Residues 1-7 form the first helix, 8-11...

only 12% of the cell-cycle genes were detected. The genes detected as periodically expressed were found to have a statistically significant overrepresentation of known cell-cycle regulated sequence motifs. One known sequence motif and 18 putative motifs, previously not associated with periodic expressio...
–In the opening section breathless, ascending, scalelike motifs keep being cut short, only to start over. Scalene: of a triangle having three sides of different lengths. –Finally, the scalenes include the anterior scalene, middle scalene, and posterior scalene. Scaley: having the body covered...
where ( α ( i ) , β ( i ) ) is good for π if π accepts α ( i ) and rejects β ( i ) We prove that the BCM problem is NP-complete even for a very simple type Ω 1 =2 ∑ {θ}, which is used, in practice, for describing protein motifs in the PROSITE database. ...
However, the much larger size of the injection system may be a disadvantage when considering tissue penetration. 5. Conclusions The broad knowledge about bacterial protein toxins, their mode of action, cellular receptors, membrane insertion motifs, pathways into the cytosol, substrate specificity, and...
Swapping of active site motifs (Ile-Asp and Asp-Ile) between a rice C-GT and a pear O-GT showed that I117D and D118I substitutions in the pear O-GT double mutant led to the 100% formation of the C-glucoside nothofagin. Although the double mutant (D120I/I121D) of pear O-GT ...
