Ribosome half life
WebbmRNA's chemical half-life can be longer than its functional half-life, but not vice versa. Most mRNAs in Escherichia coli decay with functional half-lives close to 2 min at 37 °C, … Webb21 okt. 2024 · As ribosomal proteins are believed to be degraded when not assembled into ribosomes 57,58, the shorter half-life of exchanging RPs might be due to their faster turn-over in the unbound state.
