The damage to books that is commonly attributed to "bookworms" is often caused by the larvae of various types of insects, including beetles, moths, and cockroaches, which may bore or chew through books seeking food. The damage is not caused by any species of worm. Some such larvae exhibit a superficial resemblance to worms and are the likely ...
Protein dynamics and conformational changes allow proteins to function as nanoscale biological machines within cells, often in the form of multi-protein complexes. [14] Examples include motor proteins, such as myosin, which is responsible for muscle contraction, kinesin, which moves cargo inside cells away from the nucleus along microtubules ...
Capitalizing on the World Wide Web, WormBook links in-text references (e.g. genes, alleles, proteins, literature citations) with primary biological databases such as WormBase and PubMed. C. elegans was the first multicellular organism to have its genome sequenced [6] and is a model organism for studying developmental genetics and neurobiology.
In a 2021 study comparing the nutrition of 10 varieties of edible insects to the 10 most commonly eaten animal proteins, mealworms, moths and mopane worms ranked the highest in protein, ranging 23 ...
Protein–protein interactions (PPIs) are physical contacts of high specificity established between two or more protein molecules as a result of biochemical events steered by interactions that include electrostatic forces, hydrogen bonding and the hydrophobic effect. Many are physical contacts with molecular associations between chains that ...
Polypeptides include proteins and shorter polymers of amino acids; some major examples include collagen, actin, and fibrin. Polysaccharides are linear or branched chains of sugar carbohydrates; examples include starch, cellulose, and alginate.
As well as the triose isomerase ribbon drawing at the right, other hand-drawn examples depicted prealbumin, flavodoxin, and Cu,Zn superoxide dismutase. In 1982, Arthur M. Lesk and co-workers first enabled the automatic generation of ribbon diagrams through a computational implementation that uses Protein Data Bank files as input. [7]
Polyketides are synthesized by multienzyme polypeptides that resemble eukaryotic fatty acid synthase but are often much larger. [4] They include acyl-carrier domains plus an assortment of enzymatic units that can function in an iterative fashion, repeating the same elongation/modification steps (as in fatty acid synthesis), or in a sequential ...
