Crystallization and preliminary X-ray analysis of inorganic pyrophosphatase from the hyperthermophilic archaeon Pyrococcus horikoshii OT3.
Inorganic pyrophosphatase (PPase; EC 3.6.1.1) from the hyperthermophile Pyrococcus horikoshii was crystallized by the hanging-drop vapour-diffusion method at pH 5.0 using polyethyleneglycol 4000 as the precipitant. The crystal belongs to space group P2(1)2(1)2, with unit-cell parameters a = 71.7, b = 86.5, c = 92.5 A, alpha = beta = gamma = 90 degrees. There are two molecules in the asymmetric ...
متن کاملIdentification of nucleotide residues essential for RNase P activity from the hyperthermophilic archaeon Pyrococcus horikoshii OT3.
Ribonuclease P (RNase P) is involved in the processing of the 5' leader sequence of precursor tRNA (pre-tRNA). We have found that RNase P RNA (PhopRNA) and five proteins (PhoPop5, PhoRpp21, PhoRpp29, PhoRpp30, and PhoRpp38) reconstitute RNase P activity with enzymatic properties similar to those of the authentic ribozyme from the hyperthermophilic archaeon Pyrococcus horikoshii OT3. We report h...
متن کاملNovel bifunctional hyperthermostable carboxypeptidase/aminoacylase from Pyrococcus horikoshii OT3.
Genome sequencing of the thermophilic archaeon Pyrococcus horikoshii OT3 revealed a gene which had high sequence similarity to the gene encoding the carboxypeptidase of Sulfolobus solfataricus and also to that encoding the aminoacylase from Bacillus stearothermophilus. The gene from P. horikoshii comprises an open reading frame of 1,164 bp with an ATG initiation codon and a TGA termination codo...
متن کاملCrystal Structural and Functional Analysis of the Putative Dipeptidase from Pyrococcus horikoshii OT3
The crystal structure of a putative dipeptidase (Phdpd) from Pyrococcus horikoshii OT3 was solved using X-ray data at 2.4 A resolution. The protein is folded into two distinct entities. The N-terminal domain consists of the general topology of the alpha/beta fold, and the C-terminal domain consists of five long mixed strands, four helices, and two 3(10) helices. The structure of Phdpd is quite ...
متن کاملDivergence of the hyperthermophilic archaea Pyrococcus furiosus and P. horikoshii inferred from complete genomic sequences.
Divergence of the hyperthermophilic Archaea, Pyrococcus furiosus and Pyrococcus horikoshii, was assessed by analysis of complete genomic sequences of both species. The average nucleotide identity between the genomic sequences is 70-75% within ORFs. The P. furiosus genome (1.908 mbp) is 170 kbp larger than the P. horikoshii genome (1.738 mbp) and the latter displays significant deletions in codi...
