N-Myristoyl transferase-mediated labelling using a substrate modified with an azide or alkyne tag is described as an efficient and site-selective method for the introduction of a bioorthogonal tag at the N-terminus of a recombinant protein. The procedure may be performed in vitro, or in a single over-expression/tagging step in vivo in bacteria; tagged… (More)
Type II fatty acid biosynthesis represents an attractive target for the discovery of new antimalarial drugs. Previous studies have identified malarial ENR (enoyl acyl-carrier-protein reductase, or FabI) as the target for the antiseptic triclosan. In the present paper, we report the biochemical properties and 1.5 A (1 A=0.1 nm) crystal structure of OAR… (More)
N-Myristoyl transferase-mediated modification with azide-bearing substrates is introduced as a highly selective and practical method for in vitro and in vivo N-terminal labelling of a recombinant protein using bioorthogonal ligation chemistry.
The pivotal role of proteases in many diseases has generated considerable interest in their basic biology, and in the potential to target them for chemotherapy. Although fundamental to the initiation and progression of diseases such as cancer, diabetes, arthritis and malaria, in many cases their precise role remains unknown. Activity-based chemical… (More)
