摘要:
Bacillus subtilis ATCC 6633 produces the lipid II targeting lantibiotic subtilin. For self-protection these gram-positive bacteria express a cluster of four self-immunity proteins named SpaIFEG. SpaI is a 16.8 kDa lipoprotein which is attached to the outside of the cytoplasmic membrane via a covalently linked diacylglycerol anchor. Together with the ABC-transporter SpaFEG, SpaI protects the membrane from subtilin insertion and there is evidence for a direct interaction of SpaI with subtilin. As a prerequisite for further structural studies of SpaI and the SpaI/subtilin complex we report here the full H-1, N-15, C-13 chemical shift assignment for a stable 14.9 kDa C-terminal fragment of SpaI.
