متن کاملBiotinylation in the hyperthermophile Aquifex aeolicus.
Biotin protein ligase (BPL) catalyses the biotinylation of the biotin carboxyl carrier protein (BCCP) subunit of acetyl CoA carboxylase and this post-translational modification of a single lysine residue is exceptionally specific. The exact details of the protein-protein interactions involved are unclear as a BPL:BCCP complex has not yet been isolated. Moreover, detailed information is lacking ...
متن کاملCrystal structure of conserved hypothetical protein Aq1575 from Aquifex aeolicus.
The crystal structure of a conserved hypothetical protein, Aq1575, from Aquifex aeolicus has been determined by using x-ray crystallography. The protein belongs to the domain of unknown function DUF28 in the Pfam and PALI databases for which there was no structural information available until now. A structural homology search with the DALI algorithm indicates that this protein has a new fold wi...
متن کاملA robust metallo-oxidase from the hyperthermophilic bacterium Aquifex aeolicus.
The gene, Aquifex aeolicus AAC07157.1, encoding a multicopper oxidase (McoA) and localized in the genome as part of a putative copper-resistance determinant, has been cloned, over-expressed in Escherichia coli and the recombinant enzyme purified to homogeneity. The purified enzyme shows spectroscopic and biochemical characteristics typical of the well-characterized multicopper oxidase family of...
متن کاملThe hyperthermophilic nature of the metallo-oxidase from Aquifex aeolicus.
The stability of the Aquifex aeolicus multicopper oxidase (McoA) was studied by spectroscopy, calorimetry and chromatography to understand its thermophilic nature. The enzyme is hyperthermostable as deconvolution of the differential scanning calorimetry trace shows that thermal unfolding is characterized by temperature values at the mid-point of 105, 110 and 114 degrees C. Chemical denaturation...
