Synthesis of (−)−deoxypodophyllotoxin and (−)−epipodophyllotoxin via a multi-enzyme cascade in E. coli

open access: yesMicrobial Cell Factories, 2021
Background The aryltetralin lignan (−)−podophyllotoxin is a potent antiviral and anti-neoplastic compound that is mainly found in Podophyllum plant species. Over the years, the commercial demand for this compound rose notably because of the high clinical

A minimal biochemical route towards de novo formation of synthetic phospholipid membranes. [PDF]

open access: yes, 2019
All living cells consist of membrane compartments, which are mainly composed of phospholipids. Phospholipid synthesis is catalyzed by membrane-bound enzymes, which themselves require pre-existing membranes for function.

Structural and Functional Adaptation of Vancomycin Resistance VanT Serine Racemases

open access: yesmBio, 2015
Vancomycin resistance in Gram-positive bacteria results from the replacement of the d-alanyl–d-alanine target of peptidoglycan precursors with d-alanyl–d-lactate or d-alanyl–d-serine (d-Ala-d-Ser), to which vancomycin has low binding affinity.

Red blood cells contain enzymatically active GPx4 whose abundance anticorrelates with hemolysis during blood bank storage

open access: yesRedox Biology, 2021
The antioxidant function of the phospholipid hydroperoxide glutathione peroxidase (GPx4) is vital for the homeostasis of many cell types, from neoplastic cells to normal erythroid precursors.

Biochemistry of Human Axilla Malodor and Chemistry of Deodorant Ingredients

open access: yesCHIMIA, 2007
Key human axilla malodorants are hexenoic acid (3) and 3-hydroxy-3-methyl-hexanoic acid (5), accompanied by some 25 structurally related hydroxyalkanoic acids and alkenoic acids.

Enzymic Cross-Linkage of Monomeric Extensin Precursors in Vitro [PDF]

open access: yesPlant Physiology, 1988
Rapidly growing tomato (Lycopersicon esculentum) cell suspension cultures contain transiently high levels of cell surface, salt-elutable, monomeric precursors to the covalently cross-linked extensin network of the primary cell wall. Thus, we purified a highly soluble monomeric extensin substrate from rapidly growing cells, and devised a soluble in ...

From Zn to Mn: the study of novel manganese-binding groups in the search for new drugs against tuberculosis. [PDF]

open access: yes, 2011
In most eubacteria, apicomplexans, and most plants, including the causal agents for diseases such as malaria, leprosy, and tuberculosis, the methylerythritol phosphate pathway is the route for the biosynthesis of the C(5) precursors to the essential ...

Aromatase Activity and Bone Loss in Men

open access: yesJournal of Osteoporosis, 2011
Aromatase is a specific component of the cytochrome P450 enzyme system responsible for the transformation of androgen precursors into estrogens. This enzyme is encoded by the CYP19A1 gene located at chromosome 15q21.2, that is, expressed in ovary and ...

The role of human Dicer-dsRBD in processing small regulatory RNAs. [PDF]

open access: yesPLoS ONE, 2012
One of the most exciting recent developments in RNA biology has been the discovery of small non-coding RNAs that affect gene expression through the RNA interference (RNAi) mechanism.
