Accession

GenProp0665

Name

peptide chain release operon, RctB-like/PrfH

Type

SYSTEM

Description

This genome property describes a novel two-gene operon that consists of PrfH, which is a member of the bacterial class I peptide chain release factors, and a homolog of RctB, which is a protein of unknown function thought suggest to act in RNA processing.

JCVI Role

Translation factors
