The extreme C terminus of the ABC protein DrrA contains unique motifs involved in function and assembly of the DrrAB complex
H Zhang, P Pradhan, P Kaur - Journal of Biological Chemistry, 2010 - ASBMB
Two novel regulatory motifs, LDEVFL and C-terminal regulatory Glu (E)-rich motif (CREEM),
are identified in the extreme C terminus of the ABC protein DrrA, which is involved in direct
interaction with the N-terminal cytoplasmic tail of the membrane protein DrrB and in
homodimerization of DrrA. Disulfide cross-linking analysis showed that the CREEM and the
region immediately upstream of CREEM participate directly in forming an interaction
interface with the N terminus of DrrB. A series of mutations created in the LDEVFL and …
