FeMo cofactor (FeMoco) biosynthesis is one of the most complicated processes in metalloprotein biochemistry. Here we show that Mo and homocitrate are incorporated into the Fe/S core of the FeMoco precursor while it is bound to NifEN and that the resulting fully complemented, FeMoco-like cluster is transformed into a mature FeMoco upon transfer from NifEN to MoFe protein through direct protein-p...
The synthetic models for the structures, spectroscopic properties and catalytic activities of metalloprotein active sites have been reviewed. Calixarenes were used as new biomimetic catalysts because of their advantage of providing preorganiiation of the catalytic group, which can bind the substrate dynamically that results in fast turnover and fast release of the products. Functional and struc...
This commentary outlines a protein engineering approach as an alternative to immobilisation developed in our laboratory. We use a recombinant silk protein into which metal active sites can be incorporated to produce solid-state metalloprotein materials. The silk protein directly coordinates to the metal centres providing control over their reactivity akin to that seen in naturally occurring met...
We describe the computational design of a single-chain four-helix bundle that noncovalently self-assembles with fully synthetic non-natural porphyrin cofactors. With this strategy, both the electronic structure of the cofactor as well as its protein environment may be varied to explore and modulate the functional and photophysical properties of the assembly. Solution characterization (NMR, UV-v...
