| Type: | Domain | Name: | ABC transporter, BtuC-like |
| Description: | This entry represents a domain found in some ABC transporter permease proteins, such as BtuC (involved in vitamin B12 uptake) and metal-chelatin transporters []. It consists of a multihelical, complex architecture with several transmembrane helices.ABC transporter BtuCD consists of two ATP-binding cassettes (BtuD) and two membrane-spanning subunits (BtuC). The BtuC subunits provide 20 transmembrane helices grouped around a translocation pathway that is closed to the cytoplasm by a gate region. A prominent cytoplasmic loop of BtuC forms the contact region with the ATP-binding cassette []. | Short Name: | ABC_BtuC-like |
