The scaffolding around the active site in enzymes serves many functions, from delivering electrons, ions and gases to providing substrate specificity.  This work will describe the addition of amino acids to the outer coordination sphere of the successful Ni-P2N2 hydrogen production catalysts.  This is a first step in incorporating a larger outer coordination sphere and will demonstrate the impact that the region far from the active site can have, where rates both two times faster and 10 times slower than the parent catatlyst are observed.  Mechanistic implications will be discussed.
