Enzyme-Catalyzed Kinetic Resolution of Chiral Precursors to Antiviral Prodrugs [PDF]
Nucleoside analogues are among the most common medications given for the treatment of viral infections and cancers. The therapeutic effectiveness of nucleoside analogues can be dramatically improved by phosphorylation. The ProTide approach was developed using a phosphorylated nucleoside that is masked by esterification with an amino acid and phenol ...

Biogenesis of mitochondrial c-type cytochromes [PDF]
Cytochromesc andc 1 are essential components of the mitochondrial respiratory chain. In both cytochromes the heme group is covalently linked to the polypeptide chain via thioether bridges. The location of the two cytochromes is in the intermembrane space;

Enzyme-triggered Radical Reactions: Another Approach For Tin-free Radical Chemistry
The system laccase/mediator/dioxygen is able to trigger radical reactions with radical precursors which are not natural substrates of this enzyme.

Substrate- and species-specific processing enzymes for chloroplast precursor proteins [PDF]
Using different precursors of chloroplast proteins and stromal extracts from both Chlamydomonas reinhardii and pea chloroplasts, we analysed the specificity of stroma-localized processing peptidases. By gel filtration of a stromal extract from isolated Chlamydomonas chloroplasts, fractions could be separated containing enzymic activities for processing

HS1BP3 negatively regulates autophagy by modulation of phosphatidic acid levels
Autophagy must be tightly controlled at each step of the process. Here the authors show that HS1BP3 binds phosphatidic acid (PA) at autophagosome precursors and negatively regulates autophagosome formation by modulating the activity and localization of ...

Functional analysis of the Lactococcus lactis galU and galE genes and their impact on sugar nucleotide and exopolysaccharide biosynthesis [PDF]
We studied the UDP-glucose pyrophosphorylase (galU) and UDP-galactose epimerase (galE) genes of Lactococcus lactis MG1363 to investigate their involvement in biosynthesis of UDP-glucose and UDP-galactose, which are precursors of glucose- and galactose ...

Biocatalysis as Useful Tool in Asymmetric Synthesis: An Assessment of Recently Granted Patents (2014–2019) [PDF]
The broad interdisciplinary nature of biocatalysis fosters innovation, as different technical fields are interconnected and synergized. A way to depict that innovation is by conducting a survey on patent activities.

Enzymic Synthesis of Lignin Precursors [PDF]
Isoenzyme 2 of cinnamyl‐alcohol dehydrogenase from soybean suspension cultures was purified about 3800‐fold to apparent homogeneity by an improved purification procedure involving biospecific elution of the enzyme from a NADP+‐agarose column. On sodium dodecylsulfate gels the dehydrogenase showed only one protein band with Mr 40000 ± 500.The enzyme is ...
