Crystal Structure of a Nicotinate Phosphoribosyltransferase from Thermoplasma acidophilum [PDF]

open access: yesJournal of Biological Chemistry, 2005
We have determined the crystal structure of nicotinate phosphoribosyltransferase from Themoplasma acidophilum (TaNAPRTase). The TaNAPRTase has three domains, an N-terminal domain, a central functional domain, and a unique C-terminal domain. The crystal structure revealed that the functional domain has a type II phosphoribosyltransferase fold that may ...

Proteomics Analysis of Thermoplasma acidophilum with a Focus on Protein Complexes [PDF]

open access: yesMolecular & Cellular Proteomics, 2007
Two-dimensional gel electrophoresis (2DE) and MALDI-TOF MS were used to obtain a global view of the cytoplasmic proteins expressed by Thermoplasma acidophilum. In addition, glycerol gradient ultracentrifugation coupled to 2DE-MALDI-TOF MS analysis was used to identify subunits of macromolecular complexes.

Quinone Profiles of Thermoplasma acidophilum HO-62 [PDF]

open access: yesJournal of Bacteriology, 2001
ABSTRACT Quinones of Thermoplasma acidophilum HO-62 were analyzed by high-performance liquid chromatography, mass spectrometry, and nuclear magnetic resonance. Menaquinone, methionaquinone, and 2- trans and 2- cis forms of thermoplasmaquinone were identified.

Cell-Free Enzymatic Conversion of Spent Coffee Grounds Into the Platform Chemical Lactic Acid

open access: yesFrontiers in Bioengineering and Biotechnology, 2019
The coffee industry produces over 10 billion kg beans per year and generates high amounts of different waste products. Spent coffee grounds (SCG) are an industrially underutilized waste resource, which is rich in the polysaccharide galactomannan, a ...

Purification and properties of pyruvate kinase fromThermoplasma acidophilum [PDF]

open access: yesFEMS Microbiology Letters, 1992
Thermoplasma acidophilum is a thermoacidophilic archaebacterium occupying a paradoxical place in phylogenetic trees (phenotypically it is a thermoacidophile but phylogenetically it classifies with the methanogens). To better understand its phylogeny, the pyruvate kinase from this organism is being investigated as a molecular marker. The enzyme has been

Architectures of archaeal GINS complexes, essential DNA replication initiation factors

open access: yesBMC Biology, 2011
Background In the early stage of eukaryotic DNA replication, the template DNA is unwound by the MCM helicase, which is activated by forming a complex with the Cdc45 and GINS proteins.

Phylogenomic analysis of proteins that are distinctive of Archaea and its main subgroups and the origin of methanogenesis

open access: yesBMC Genomics, 2007
Background The Archaea are highly diverse in terms of their physiology, metabolism and ecology. Presently, very few molecular characteristics are known that are uniquely shared by either all archaea or the different main groups within archaea.

Enzymatic Synthesis of NAD+

open access: yesCurrent Protocols, Volume 6, Issue 6, June 2026.
Abstract Nicotinamide adenine dinucleotide (NAD+) is an essential metabolite involved in numerous biological processes, functioning both as a redox cofactor in cellular energy metabolism and as a co‐substrate for NAD+‐utilizing enzymes, including sirtuins and poly(ADP‐ribose) polymerases.
