Crystal structure of theThermoplasma acidophilumprotein Ta1207 [PDF]

Acta Crystallographica Section F Structural Biology Communications, 2017
The crystal structure of the Ta1207 protein fromThermoplasma acidophilumis reported. Ta1207 was identified in a screen for high-molecular-weight protein complexes inT. acidophilum. In solution, Ta1207 forms homopentamers of 188 kDa. The crystal structure of recombinant Ta1207 solved by Se-MAD at 2.4 Å resolution revealed a complex with fivefold ...

Enzymatic Synthesis of NAD+

Current 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.

Deciphering the properties and reaction mechanism of anhydromevalonate phosphate decarboxylase, a prenylated flavin mononucleotide‐dependent enzyme in the archaeal mevalonate pathway

The FEBS Journal, Volume 293, Issue 11, Page 3303-3319, June 2026.
Characterization of anhydromevalonate phosphate decarboxylase, the UbiD‐family decarboxylase involved in the archaeal mevalonate pathway, was conducted. The enzyme is responsible for the biosynthesis of isoprenoids, such as archaeal membrane lipids, respiratory quinones, and dolichols.

The return of metabolism: biochemistry and physiology of glycolysis

Biological Reviews, Volume 101, Issue 2, Page 751-803, April 2026.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Characterization of Thermoplasma acidophilum Deoxyribonucleic Acid [PDF]

International Journal of Systematic Bacteriology, 1975
The deoxyribonucleic acid (DNA) of the mycoplasma Thermoplasma acidophilum has a base composition of 46 mol% guanine plus cytosine (G+C). Depurination can occur to the DNA in the culture conditions, giving rise to a product of lower buoyant density. This effect probably accounts for earlier descriptions of a much lower G+C content in the DNA.

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

Journal 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 ...
