The protein
Catalyzed reaction/ biological activity
acts as a kind of "leader peptide" that does or does not allow translation through a hairpin structure in the ''[gene|121A9543F5BC1CBE77D85A34099DE09F8AC63E9F|yidC2]'' mRNA [Pubmed|19779460]
[wiki|Domains]
N-terminal transmembrane domain [Pubmed|22864117]
the C-terminal domain interacts with the ribosome and arrests the own translation elongation [Pubmed|22864117]
