The small subunit is composed of two domains. The N-terminal domain shows the characteristic architecture of flavodoxin with the phosphate moiety of the flavin cofactor occupying the binding pocket of the proximal [4Fe-4S] cluster. This N-terminal domain, including the proximal cluster, is found in all [NiFe] hydrogenases and is consequently an essential feature, both structural and functional, of these enzymes. By contrast, the C-terminal domain that binds the other [FeS] clusters is less organised and more variable in [FeS] cluster content and amino acid sequence.

Weinstein et al., 1997 Eisen et al., 1998). Inspection of the dendrogram and color plot will reveal samples with closely related patterns of gene expression as well as clusters of genes with similar expression pattern. Software for this type of display is freely available. This approach has been productively applied to yeast and human expression data. It is important to note that there is an arbitrary character to the manner in which a dendrogram is drawn. Clusters can be rotated about the point of bifurcation affecting the apparent proximity of the edges of a cluster with adjacent clusters. The important information is contained in the cluster contents and their similarity. 

Cluster units cause chain transfer, most probably to styrene molecules. This conclusion is also confirmed by the correspondence between the cluster content and the specific number of double bonds in the copolymers obtained.
