Tarjetas de memoria: Protein Engineering and Development — 18 tarjetas

Protein engineering — definition?

Designing and modifying proteins for specific functions.

Rational design — role?

Uses structural knowledge to make targeted modifications.

Directed evolution — method?

Generates variants and selects desired traits via screening.

Site-directed mutagenesis — purpose?

Introduces specific amino acid changes at defined positions.

Gene editing — main tool?

CRISPR-Cas9 for precise genomic modifications.

Post-translational modification — example?

Phosphorylation alters protein activity and signaling.

Analytical technique — X-ray crystallography?

Determines 3D atomic structure of proteins.

Protein structure — hierarchy?

Primary, secondary, tertiary, quaternary levels.

Mutagenesis — purpose?

Create protein diversity for functional improvements.

Bioinformatics — role?

Predicts structures, functions, guides engineering.

PTMs — impact?

Regulate activity, localization, stability of proteins.

Engineered proteins — applications?
