NAD-dependent formate dehydrogenase (FDH) was isolated from Candida methylica (Cm) grown on 0.5% methanol. Its N-terminal amino acid (aa) sequence was determined, as was that of a commercial FDH from Candida boidinii. Degenerate oligodeoxyribonucleotides were made to the 5' region of the fdh gene from Cm using this information and to the 3' region using C-terminal aa sequence data from the methylotropic yeast, Hansenula polymorpha. An almost complete 1.1-kb fragment was amplified from Cm genomic DNA via the polymerase chain reaction (PCR). This fragment was cloned, sequenced and used to probe a Southern blot, from which a 3.4-kb EcoRI fragment containing the fdh open reading frame (ORF) was isolated. The complete nucleotide sequence of this fdh ORF was determined and corresponds to a protein of 364 aa (40,343 Da). The ORF of fdh was cloned into pKK223-3 using PCR and transformed into Escherichia coli. Enzymatically active FDH was produced to 15% of soluble E. coli protein. The deduced aa sequence of this FDH is compared to the aa sequences of four known FDH, from bacteria, yeast, fungi and plant mitochondria.

D002175	Candida	A genus of yeast-like mitosporic Saccharomycetales fungi characterized by producing yeast cells, mycelia, pseudomycelia, and blastophores. It is commonly part of the normal flora of the skin, mouth, intestinal tract, and vagina, but can cause a variety of infections, including CANDIDIASIS; ONYCHOMYCOSIS; VULVOVAGINAL CANDIDIASIS; and CANDIDIASIS, ORAL (THRUSH).

D003001	Cloning, Molecular	The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.	Molecular Cloning
D004926	Escherichia coli	A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.	Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
D005560	Formate Dehydrogenases	Flavoproteins that catalyze reversibly the reduction of carbon dioxide to formate. Many compounds can act as acceptors, but the only physiologically active acceptor is NAD. The enzymes are active in the fermentation of sugars and other compounds to carbon dioxide and are the key enzymes in obtaining energy when bacteria are grown on formate as the main carbon source. They have been purified from bovine blood. EC 1.2.1.2.
