Serum matrix metalloproteinase-9 levels and enzymatic activity in patients with anti-glomerular basement membrane disease [PDF]

open access: yesFrontiers in Medicine
BackgroundAnti-glomerular basement membrane (anti-GBM) disease is an autoimmune disorder with autoantibodies against GBM component, non-collagenous domain of the α3 chain of type IV collagen, α3(IV)NC1. Matrix metalloproteinase-9 (MMP-9) is an endogenous

Staphylococcal Enterotoxin M Exhibits Thrombin-like Enzymatic Activity [PDF]

open access: yesBiomolecules
To express and purify staphylococcal enterotoxin M (SEM) using immobilized metal affinity chromatography (IMAC), a signal peptide-truncated (ΔNsp) wild-type SEM (SEMWT) was N-terminally fused in pET-28a(+) to a polyhistidine tag (His6×-) and thrombin ...

On the Enzymatic Activation of NADH [PDF]

open access: yesJournal of Biological Chemistry, 2001
Atomic (1 A) resolution x-ray structures of horse liver alcohol dehydrogenase in complex with NADH revealed the formation of an adduct in the active site between a metal-bound water and NADH. Furthermore, a pronounced distortion of the pyridine ring of NADH was observed.

Soil enzymatic activity and wheat grain yield under cover crop systems

open access: yesPesquisa Agropecuária Tropical, 2023
For years, the impacts of using cover crops in productive systems have been measured by their relation with soil chemical and physical characteristics. Consequently, the effects on the soil microbiological characteristics have been little explored.
