Random Network Behaviour of Protein Structures

open access: yes, 2009
Geometric and structural constraints greatly restrict the selection of folds adapted by protein backbones, and yet, folded proteins show an astounding diversity in functionality.

The metabolic significance of octulose phosphates in the photosynthetic carbon reduction cycle in spinach [PDF]

open access: yes, 2006
14C-Labelled octulose phosphates were formed during photosynthetic14CO2 fixation and were measured in spinach leaves and chloroplasts. Because mono- and bisphosphates of d-glycero- d-ido-octulose are the active 8-carbon ketosugar intermediates of the L ...

Characterization of the thermophilic xylanase Fsa02490Xyn from the hyperthermophile Fervidibacter sacchari belonging to glycoside hydrolase family 10

open access: yesFEBS Open Bio, Volume 15, Issue 10, Page 1629-1642, October 2025.
Fervidibacter sacchari is a member of the bacterial phylum Armatimonadota, only a few of which have been cultivated. It is a hyperthermophilic polysaccharide degradation specialist. We show that a secreted enzyme, Fsa02490Xyn, is an endoxylanase belonging to glycoside hydrolase family 10.

Resistance to Soybean Cyst Nematode: Rhg1 [PDF]

open access: yes, 2012
The genes underlying rhg1 lie at a sometimes dominant sometimes co-dominant locus, necessary for resistance to all Hg types of the soybean (Glycine max (L.) Merr.) cyst nematode (Heterodera glycines).

Plant Triose Phosphate Isomerase Isozymes [PDF]

open access: yesPlant Physiology, 1984
We report the first complete purifications of the cytosolic and plastid isozymes of triose phosphate isomerase (TPI; EC 5.3.1.1) from higher plants including spinach (Spinacia oleracea), lettuce (Lactuca sativa), and celery (Apium graveolens). Both isozymes are composed of two isosubunits with approximate molecular weight of 27,000; in spinach and ...

Beyond Histones: Unveiling the Functional Roles of Protein Acetylation in Prokaryotes and Eukaryotes

open access: yesCell Biology International, Volume 49, Issue 10, Page 1301-1318, October 2025.
ABSTRACT Lysine acetylation plays a crucial role in cellular processes and is found across various evolutionary organisms. Recent advancements in proteomic techniques revealed the presence of acetylation in thousands of non‐histone proteins. Here, we conducted extensive meta‐analysis of 48 acetylomes spanning diverse organisms, including archaea ...

Analysis of Multiple Isoenzyme Expression Among Twenty-Two Species of Mycoplasma and Acholeplasma [PDF]

open access: yes, 1981
Crude extracts of triple-cloned, purified cultures of 22 species of Mycoplasma and Acholeplasma were examined for expression of 21 isozyme systems routinely used to type mammalian cells. Nine previously described enzymes (purine nucleoside phosphorylase,

Responses of the marine diatom Thalassiosira pseudonana to changes in CO2 concentration: a proteomic approach [PDF]

open access: yes, 2017
The concentration of CO2 in many aquatic systems is variable, often lower than the KM of the primary carboxylating enzyme Rubisco, and in order to photosynthesize efficiently, many algae operate a facultative CO2 concentrating mechanism (CCM).
