The precursor polypeptides of periplasmic proteins binding seven types of redox cofactor
have unusually long signal sequences bearing a consensus (S/T)‐R‐R‐x‐F‐L‐K motif …

The Tat (twin‐arginine translocation) system is a bacterial protein export pathway with the
remarkable ability to transport folded proteins across the cytoplasmic membrane. Preproteins …

Nitrogen is present in the environment in a number of oxidation states (Fig. 1). Interconversion
between these oxidation states is predominantly biological (Fig. 1). In this review we …

We describe the identification of two Escherichia coli genes required for the export of
cofactor‐containing periplasmic proteins, synthesized with signal peptides containing a twin …

… Examples are single-polypeptide c-type haem- and flavin-binding flavocytochromes c 33
and the c-type haem- and Cu Z copper–sulphur cluster-containing nitrous oxide reductase of …

Proteins are transported across the bacterial plasma membrane and the chloroplast thylakoid
membrane by means of protein translocases that recognize N-terminal targeting signals in …

The Tat system mediates Sec-independent transport of folded precursor proteins across the
bacterial plasma membrane or the chloroplast thylakoid membrane. Tat transport involves …

In Escherichia coli, transmembrane translocation of proteins can proceed by a number of
routes. A subset of periplasmic proteins are exported via the Tat pathway to which proteins are …

In Escherichia coli a subset of periplasmic proteins is exported through the Tat pathway to
which substrates are directed by an NH 2 -terminal signal peptide containing a consensus …

The nucleotide sequence has been determined for a twelve-gene operon of Escherichia
coli designated the hyf operon (hyfABCDEFGHIR-focB). The hyf operon is located at 55.8-56.0 …
