Noun
an amino acid that is found in many proteins (especially collagen)
Source: WordNetHIF is synthesized consititutively, and hydroxylation of at least one of two critical proline residues mediates their interaction with the von Hippel Lindau E3 ubiquitin ligase complex, which targets them for rapid degradation. Source: Internet
In humans, a common polymorphism involves the substitution of an arginine for a proline at codon position 72. Many studies have investigated a genetic link between this variation and cancer susceptibility; however, the results have been controversial. Source: Internet
Cis-trans isomerization Peptide bonds to proline, and to other N-substituted amino acids (such as sarcosine ), are able to populate both the cis and trans isomers. Source: Internet
History Richard Willstätter synthesized proline by the reaction of sodium salt of diethyl malonate with 1,3-dibromopropane in 1900. Source: Internet
However, proline is often seen as the first residue of a helix, it is presumed due to its structural rigidity. Source: Internet
In 1991, Japanese scientists created the first milk-based ACE inhibitor, in the form of a fermented milk drink, using specific cultures to liberate the tripeptide isoleucine proline -proline (IPP) from the dairy protein. Source: Internet
