Protein Variants

Protein Variants Comment Organism
DELTAN21 mutant prevents molybdo-bis(pyranopterin guanine dinucleotide) binding and results in a degenerate [3Fe-4S] clusterform being assembled Escherichia coli
R61K molybdo-bis(pyranopterin guanine dinucleotide) content is 90% of wild-type, decrease in specific activity Escherichia coli
V20Y/DELTAN21/P27G introduction of a type I Cys group, mutations eliminate both molybdo-bis(pyranopterin guanine dinucleotide) binding and detection of a FSo cluster by EPR Escherichia coli
V20Y/DELTAN21/P27G/R61K addtion of mutation R61K to mutant V20Y/DELTAN21/P27G partially rescues molybdo-bis(pyranopterin guanine dinucleotide) insertion Escherichia coli

Cofactor

Cofactor Comment Organism Structure
[4Fe-4S]-center role for the cluster in directing molybdenum cofactor assembly during enzyme maturation. The cluster is predicted to be in close proximity to the molybdo-bis(pyranopterin guanine dinucleotide) cofactor, which provides the site of dimethyl sulfoxide reduction Escherichia coli
