Abstract
In the present study, we purified and characterized three formaldehyde dismutases (Fdms) (EC 1.2.98.1) (Fdm1, Fdm2, and Fdm3) of Methylobacterium sp. FD1. These Fdms (with His-tag) were produced in the recombinant E. coli and purified by immobilized metal affinity chromatography from the E. coli extracts. In each of the three Fdms, the enzyme-bound coenzyme was nicotinamide adenine dinucleotide (NAD(H)) and the enzyme-bound metal was zinc. The quaternary structures of these Fdms were estimated as homotetrameric. The optimal pHs and temperatures of Fdm1, Fdm2, and Fdm3 were approximately 6.5, 6.0, and 6.0, and 35°C, 25°C, and 30°C, respectively. The Km values of Fdm1, Fdm2, and Fdm3 were 621, 865, and 414 mM, respectively. These results were similar to the properties of already-known Fdms. However, each of the Fdms of FD1 had methanol:p-nitroso-N,N-dimethylaniline oxidoreductase activity that is not found in already-known Fdms.

Abstract
Abstract
In the present study, formaldehyde dismutase from Methylobacterium sp. FD1 was partially purified and analyzed by nanoLC–MS/MS; it was then cloned from the genomic DNA of FD1 by PCR. The open reading frame of the formaldehyde dismutase gene of FD1 was estimated to be 1203 bp in length. The molecular weight and pI of formaldehyde dismutase (401 aa), as deduced from the FD1 gene, were calculated at 42,877.32 and 6.56, respectively. NAD(H)-binding residues and zinc-binding residues were found in the amino acid sequence of the deduced formaldehyde dismutase of FD1 by BLAST search. The resting Escherichia coli cells that were transformed with the FD1 formaldehyde dismutase gene degraded high concentrations of formaldehyde and produced formic acid and methanol that were molar equivalents of one-half of the degraded formaldehyde. The lyophilized cells of the recombinant E. coli also degraded high concentrations of formaldehyde.

Abstract
The catalytic networks of methylotrophic organisms, featuring redox enzymes for the activation of one-carbon moieties, can serve as great inspiration in the development of novel homogeneously catalyzed pathways for the interconversion of C1 molecules at ambient conditions. An imidazolium-tagged arene-ruthenium complex was identified as an effective functional mimic of the bacterial formaldehyde dismutase, which provides a new and highly selective route for the conversion of formaldehyde to methanol in absence of any external reducing agents. Moreover, secondary amines are reductively methylated by the organometallic dismutase mimic in a redox self-sufficient manner with formaldehyde acting both as carbon source and reducing agent.

Abstract
Formaldehyde dehydrogenase from Pseudomonas putida (PFDH) is a member of the zinc-containing medium-chain alcohol dehydrogenase family. The pyridine nucleotide NAD(H) in PFDH, which is distinct from the coenzyme (as cosubstrate) in typical alcohol dehydrogenases (ADHs), is tightly but not covalently bound to the protein and acts as a cofactor. PFDH can catalyze aldehyde dismutations without an external addition of NAD(H). The structural basis of the tightly bound cofactor of PFDH is unknown. The crystal structure of PFDH has been solved by the multiwavelength anomalous diffraction method using intrinsic zinc ions and has been refined at a 1.65 A resolution. The 170-kDa homotetrameric PFDH molecule shows 222 point group symmetry. Although the secondary structure arrangement and the binding mode of catalytic and structural zinc ions in PFDH are similar to those of typical ADHs, a number of loop structures that differ between PFDH and ADHs in their lengths and conformations are observed. A comparison of the present structure of PFDH with that of horse liver ADH, a typical example of an ADH, reveals that a long insertion loop of PFDH shields the adenine part of the bound NAD(+) molecule from the solvent, and a tight hydrogen bond network exists between the insertion loop and the adenine part of the cofactor, which is unique to PFDH. This insertion loop is conserved completely among the aldehyde-dismutating formaldehyde dehydrogenases, whereas it is replaced by a short turn among typical ADHs. Thus, the insertion loop specifically found among the aldehyde-dismutating formaldehyde dehydrogenases is responsible for the tight cofactor binding of these enzymes and explains why PFDH can effectively catalyze alternate oxidation and reduction of aldehydes without the release of cofactor molecule from the enzyme.

Abstract
Formaldehyde dehydrogenase (PFDH) was isolated from the creatinine-decomposing bacterium Pseudomonas putida, and its gene has been cloned. PFDH is unique because it was the only enzyme that catalyzed the dehydrogenation of formaldehyde without glutathione. PFDH belongs to a zinc-containing alcohol dehydrogenase family. Quantitative analysis of the reaction products using NMR revealed that the enzyme is not simply a dehydrogenase but is an aldehyde dismutase catalyzing a simultaneous conversion of both aldehyde to carboxylate and aldehyde to alcohol. The enzyme contains a tightly bound cofactor of NAD+/NADH per subunit and is classified as a nicotinoprotein. The enzyme reaction can proceed without external addition of the nucleotide cofactor. The formaldehyde was crystallized using the hanging-drop vapor diffusion method with ammonium sulfate as a precipitant. The crystal structure was determined using the multiwavelength anomalous diffraction method with intrinsic zinc ions. The overall structure of PFDH is similar to that of a classic horse liver alcohol dehydrogenase. However, a comparison of these structures indicated that the insertion loop specifically found in PFDH may be responsible for the tight binding of the cofactor, thereby making PFDH a dismutase.

Abstract
A cDNA from Arabidopsis thaliana resembling S-formylglutathione hydrolase (SFGH), an enzyme with putative roles in formaldehyde detoxification in animals and microorganisms, has been cloned and expressed in Escherichia coli. The purified recombinant Arabidopsis enzyme (AtSFGH) was a dimer composed of 31-kDa subunits. Like SFGHs from other sources, AtSFGH had thioesterase activity toward S-formylglutathione and carboxyesterase activity toward 4-methylumbelliferyl acetate. Unlike other SFGHs, the enzyme from Arabidopsis actively hydrolyzed S-acetylglutathione. AtSFGH activity was inhibited by heavy metals and sulfhydryl alkylating agents, but was insensitive to serine hydrolase inhibitors, suggesting that the enzyme was a cysteine-dependent hydrolase. Although Atsfgh transcripts were determined in plants and cultures of Arabidopsis, the respective enzyme could not be detected in planta after the esterase activities present were resolved using isoelectric focusing. Instead, Arabidopsis contained several carboxyesterases active toward alpha-naphthyl acetate, which were all sensitive to inhibition by the serine hydrolase inhibitor paraoxon.

Abstract
The overexpression of fdm, which encodes the formaldehyde dismutase from Pseudomonas putida F61, resulted in the formation of inclusion bodies made up of aggregated enzyme, leaving little activity in the soluble fraction of the transformant cells. On the other hand, coexpression of groESL along with fdm facilitated in vivo solubilization of the enzyme protein in its active form. When coexpressed with groESL, formaldehyde dismutase purified from E. coli had the same crystalline form (i.e., a regular octahedron) as the native enzyme, and like the native enzyme, it bound 1 mol of NAD(H) and 2 mol of zinc in each subunit.

Abstract
Downstream of flhA, the Paracoccus denitrificans gene encoding glutathione-dependent formaldehyde dehydrogenase, an open reading frame was identified and called fghA. The gene product of fghA showed appreciable similarity with human esterase D and with the deduced amino acid sequences of open reading frames found in Escherichia coli, Haemophilus influenzae, and Saccharomyces cerevisiae. Mutating fghA strongly reduced S-formylglutathione hydrolase activity. The mutant was unable to grow on methanol and methylamine, indicating that the enzyme is essential for methylotrophic growth. S-Formylglutathione hydrolase appears to be part of a formaldehyde detoxification pathway that is universal in nature.

Abstract
A DNA fragment of 550 bp was specifically amplified by PCR with primers based on the N-terminal sequence of the purified 3-hexulose-6-phosphate synthase from Methylomonas aminofaciens 77a and on that of a lysyl endopeptidase-derived peptide. Using this PCR product as a probe, a gene coding for 3-hexulose-6-phosphate synthase in M. aminofaciens 77a chromosomal DNA was cloned in Escherichia coli JM109. Sequencing analysis revealed that the gene encoding 3-hexulose-6-phosphate synthase contained a 624-bp open reading frame, encoding a protein composed of 208 amino acid residues with a calculated relative molecular mass of 21,224.
