PG - 365-71 AB - The NAD-dependent glutamate dehydrogenase (GluDH) gene from the hyperthermophilic archaeon Pyrobaculum islandicum was cloned and expressed in Escherichia coli. Analysis of the nucleotide sequence revealed an open reading frame of 1266 bp encoding a protein of 421 amino acids with a molecular weight of 46,905. In the alignment of the amino acid sequence with those of mesophilic Clostridium symbiosum NAD-dependent GluDH and hyperthermophilic NADP-dependent enzymes from Thermococcus profundus and Pyrococcus furiosus, substitutions in the residues involved in dinucleotide binding were observed. On the other hand, the residues involved in glutamate binding were well conserved. This is the first description of the primary structure of NAD-dependent GluDH in hyperthermophilic archaea.
