释义

Definition of chaperonin in English:

chaperonin

nounˌʃapəˈrəʊnɪnˌSHapəˈrōnən
Biochemistry
  • A protein that aids the assembly and folding of other protein molecules in living cells.

    〔生化〕陪伴蛋白

    Example sentencesExamples
    • The best studied chaperone is the bacterial chaperonin, GroEL, a large protein shaped like a double ring with dyad symmetry under certain conditions.
    • In addition to folding new proteins, chaperonins also re-fold old proteins which have somehow gotten twisted out of shape.
    • The biogenesis of microtubules in the cell comprises a series of complex steps, including protein-folding reactions catalyzed by chaperonins.
    • However, not all complexes are so constrained, as illustrated by the evolution of the archael thermosome - yet another chaperonin composed of multiple rings of subunits.
    • Further investigation, especially into the mechanical properties of misfolded proteins, is essential to clarify the functional mechanics of the chaperonin.

Origin

1990s: from chaperone + -in.
