post-translational modification
1post-translational modification — Changes that occur to proteins after peptide bond formation has occurred. Examples include glycosylation, acylation, limited proteolysis, phosphorylation, isoprenylation …
2post-translational modification — The addition of specific chemical residues to a protein after it has been translated. Common residues are phosphate groups (phosphorylation) and sugars (glycosylation) …
3Posttranslational modification — (PTM) is the chemical modification of a protein after its translation. It is one of the later steps in protein biosynthesis for many proteins.A protein (also called a polypeptide) is a chain of amino acids. During protein synthesis, 20 different… …
4Gene expression — For vocabulary, see Glossary of gene expression terms. For a non technical introduction to the topic, see Introduction to genetics. Genes are expressed by being transcribed into RNA, and this transcript may then be translated into protein. Gene… …
5Regulation of gene expression — Gene modulation redirects here. For information on therapeutic regulation of gene expression, see therapeutic gene modulation. For vocabulary, see Glossary of gene expression terms Diagram showing at which stages in the DNA mRNA protein pathway… …
6Molecular biology — (pronounced /məˈlɛkjʊlər .../) is the branch of biology that deals with the molecular basis of biological activity. This field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology… …
7Proteomics — is the large scale study of proteins, particularly their structures and functions.cite journal |author=Anderson NL, Anderson NG |title=Proteome and proteomics: new technologies, new concepts, and new words |journal=Electrophoresis |volume=19… …
8Circadian oscillator — Circadian oscillators are components of the biological clocks that regulate the activities of organisms in relation to environmental cycles and provide an internal temporal framework.[1] All circadian clocks, regardless of phylogenetic origin,… …
9Polyadenylation — Typical structure of a mature eukaryotic mRNA Polyadenylation is the addition of a poly(A) tail to an RNA molecule. The poly(A) tail consists of multiple adenosine monophosphates; in other words, it is a stretch of RNA that has only adenine bases …
10Chemical biology — is a scientific discipline spanning the fields of chemistry and biology that involves the application of chemical techniques and tools, often compounds produced through synthetic chemistry, to the study and manipulation of biological systems.… …
