Molecular mimicry is thus occurring between two recognized peptides that have similar antigenic surfaces in the absence of primary sequence homology. For example, specific single amino acid residues such as cysteine (creates di-sulfide bonds), arginine or lysine (form multiple hydrogen bonds), could be essential for T cell cross-reactivity.
Chemical mimicry. Spider orchids mimic the odours of female mining bees. Chemical mimicry (or molecular mimicry) is a type of biological mimicry involving the use of chemicals to dupe an operator. A chemical mimic dupes an operator (e.g. a predator) by showing an adaptive chemical resemblance to an object of its environment and as a consequence ...
In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. In the simplest case, as in Batesian mimicry, a mimic resembles a model, so as to deceive a dupe, all three being of ...
Phagomimicry, as the name suggests, is a type of chemical mimicry. Many organisms have evolved to use mimicry as it is a highly successful mechanism of chemical defense. [47] Sea hares, when attacked, quickly release a fog of chemicals into the surrounding environment. The chemical cloud consists of two main parts: the ink and the opaline. [61]
A peptidomimetic is a small protein-like chain designed to mimic a peptide. [ 1][ 2] They typically arise either from modification of an existing peptide, or by designing similar systems that mimic peptides, such as peptoids and β-peptides. Irrespective of the approach, the altered chemical structure is designed to advantageously adjust the ...
Biomimetics or biomimicry is the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems. [ 2][ 3][ 4] The terms "biomimetics" and "biomimicry" are derived from Ancient Greek: βίος ( bios ), life, and μίμησις ( mīmēsis ), imitation, from μιμεῖσθαι ( mīmeisthai ), to ...
There are few well-studied examples of mimicry in vertebrates. [1] Still, many of the basic types of mimicry apply to vertebrates, especially among snakes. Batesian mimicry is rare among vertebrates but found in some reptiles (particularly snakes) and amphibians. [2] [3] Müllerian mimicry is found in some snakes, birds, amphibians, and fish.
Molecular biology / məˈlɛkjʊlər / is a branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including biomolecular synthesis, modification, mechanisms, and interactions. [ 1][ 2][ 3] Though cells and other microscopic structures had been observed in living organisms as early as the ...
