ECMDB

Identification

Name:

Sec-independent protein translocase protein TatB

Synonyms:

Not Available

Gene Name:

tatB

Enzyme Class:

Not Available

Biological Properties

General Function:

protein transport by the Tat complex

Specific Function:

Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin-arginine motif in their signal peptide across membranes. Together with TatC, TatB is part of a receptor directly interacting with Tat signal peptides. TatB may form an oligomeric binding site that transiently accommodates folded Tat precursor proteins before their translocation.
