THE BIOSYNTHESIS OF SUCROSE

Journal of Biological Chemistry, 1955
The enzyme, which was named sucrose phosphorylase, has not been found in plant tissues (4), and thus the mechanism of sucrose synthesis remains obscure. Evidence obtained from tracer experiments led Buchanan et al. (5, 6) to assume that in plants sucrose phosphate is formed from UDPG’ and fructose-l-phosphate.

Environmental degradation of plastics containing pro-oxidant additives and their toxicological impact in desert ecosystems

Case Studies in Chemical and Environmental Engineering
The accumulation of single-use plastic materials poses significant environmental and waste management challenges. Pro-oxidant additive-containing (PAC) plastics have been introduced in many regions to mitigate these impacts.

Thiohistidine Biosynthesis

CHIMIA, 2013
Ergothioneine and ovothiol A are sulfur-containing histidine derivatives produced by microorganisms including Mycobacterium tuberculosis, Trypanosoma cruzi or Erwinia amylovora and may also play important roles in human physiology. Based on our recent identification of thiohistidine biosynthetic enzymes from Mycobacterium smegmatis and ...

A new type of DNA phosphorothioation-based antiviral system in archaea

Nature Communications, 2019
The prokaryote defence system Dnd relies on phosphorothioation (PT) of DNA backbone to distinguish between self and non-self DNA. Here, Xiong et al. describe a previously uncharacterized PT-based antiviral system that is independent of the canonical Dnd ...

Puromycin A, B and C, cryptic nucleosides identified from Streptomyces alboniger NRRL B-1832 by PPtase-based activation

Synthetic and Systems Biotechnology, 2018
Natural product discovery is pivot for drug development, however, this endeavor is often challenged by the wide inactivation or silence of natural products biosynthetic pathways.
