The two available crystallographic structures of cobalamin dependent enzymes, the 27 kDa fragment of the methylcobalamin-dependent enzyme, methionine synthase, from Escherichia coli [Drennan, C. L. et al. Science 1994, 266, 1669] and the 5‘-deoxyad

FosA is a manganese metalloglutathione transferase that confers resistance to the broad-spectrum antibiotic fosfomycin, which contains a phosphonate group. The active site of this enzyme consists of a high-spin Mn(2+) ion coordinated by endogenous li

Ethylene is a plant hormone involved in all stages of growth and development, including regulation of germination, responses to environmental stress, and fruit ripening. The final step in ethylene biosynthesis, oxidation of 1-aminocyclopropane-1-carb

FosA is a manganese metalloglutathione transferase that confers resistance to the broad-spectrum antibiotic fosfomycin, (1R,2S)-epoxypropylphosphonic acid. The reaction catalyzed by FosA involves the attack by glutathione on fosfomycin to yield the p

Streptomyces coelicolor CH999/pJRJ2 harbors a plasmid encoding DEBS(KS1 degrees ), a mutant form of 6-deoxyerythronolide B synthase that is blocked in the formation of 6-deoxyerythronolide B (1, 6-dEB) due to a mutation in the active site of the keto

We here report the first direct evidence addressing the possible involvement of Mo in substrate interactions during catalytic turnover. When the alpha-70(Ile) MoFe protein is freeze-trapped during H(+) reduction under Ar, the majority of the resting

E. coli ribonucleotide reductase (RNR), composed of the homodimeric subunits alpha2 and beta2, catalyzes the conversion of nucleotides to deoxynucleotides via complex radical chemistry. The radical initiation process involves a putative proton-couple
