Metabolic engineering is often hampered by non-linear kinetics and allosteric regulatory mechanisms. Here, the authors construct a quantitative model for the pentose degradation Weimberg pathway in Caulobacter crescentus and demonstrate its biotechno

In contrast to automated machines, manual assembly still lacks real-time process monitoring, concepts for short-term control and the possibility to quickly adapt the assembly systems setup. This paper describes different approaches which consider obj

Oncogenic Ras mutations occur in more than 30 % of human cancers. K-Ras4B is the most frequently mutated isoform of Ras proteins. Development of effective K-Ras4B inhibitors has been challenging, hence new approaches to inhibit this oncogenic protein
