MoFe protein 

2 pairs of identical subunits (tetramer, nif D & nif K)

A total of MW 180 ~ 235kD

Each subunit has 2 Mo-Fe-S clusters.

Both Fe proteins and MoFe proteins are sensitive to O2.

The Hutchinsonian niche is an "n-dimensional hypervolume", where the dimensions are environmental conditions and resources

                                   Richard hypothesis 

d/w = resource separation ratio.

d/w < 1, species cannot coexist;

1 < d/w < 3, there will be some competition between species

d/w > 3, species coexist harmoniously
