Green Biotech

Recently, many efforts have been made to improve growth and yield of crop plants. CO2 fixation in plants is primarily catalyzed by the enzyme ribulose-1,5-bisphosphate carboxylase (Rubisco). The inherent inefficiency of Rubisco necessitates an additional metabolic process termed photorespiration, which results in the loss of carbon and energy. In fact, it has been estimated that plants lose approximately 25% of the fixed carbon due to photorespiration. Despite several attempts to improve ...

Core-shell catalyst design for improved heat management with highly exothermic reactions

Ref.-No.: 1402-5768-LC

Processes and Methods (incl. Screening)
New Materials

Prof. Kai Sundmacher and co-workers at the MPI for Dynamics of Complex Technical Systems developed a novel core-shell catalyst design with a highly active catalyst core surrounded by an inert, low-permeability shell. The new catalyst design leads to an intrinsic heat management that avoids hotspots in strongly exothermic reactions. This allows faster reactor start-up and shut-down and makes the catalysts suitable for rapid load changes in discontinuous processes.

Generation of induced pluripotent stem cells with one or two reprogramming factors

Processes and Methods (incl. Screening) : Life Sciences-HTS/HCS
Nucleic Acid-, Protein and Cell-related Technologies : Cell related

The cellular identity of mature cells that are confined in a specialized genetic expression profile can be overcome by introducing just a few genes that encode for so-called reprogramming factors [1]. By means of this intervention, also known as reprogramming, the cells then become pluripotent and represent induced pluripotent stem cells (iPS cells) [1]. Nowadays, numerous new cell culture models have been established based on reprogramming protocols that yield iPS cells. Such cell culture models ...

Genome-Editing-Technologies - Cas9 double mutant with improved specificity compared to wild-type

Nucleic Acid-, Protein and Cell-related Technologies

The RNA-programmable DNA-endonuclease Cas9 is widely used for genome engineering, where a high degree of specificity is required. Though this is a mechanism well controlled by canonical base-pairing, there is evidence that Cas9 does accept mismatches under certain circumstances.
This might be seen as a threat to precision needed in genome engineering at least in environments where such high precision is ultimately needed and acceptance of mismatches needs to be avoided, e.g.: cellular gene ...

Nucleic Acid-, Protein and Cell-related Technologies

Precise genome editing demands for homology-directed repair (HDR) by aiming to introduce a new double stranded DNA substituting for a homologous sequence but partially defect one. This substrate dependent reaction does compete with direct non-homologous end joining (NHEJ) of the double strand breaks. NHEJ is error-prone and is therefor mainly used for gene inactivation.
The rate of NHEJ is directly limiting the rate of HDR. For this reason HDR in vitro does occur on a very low level only and ...

GOLD gRNA - allows robust genome editing regardless of spacer sequence composition by super stable hairpin technology

Nucleic Acid-, Protein and Cell-related Technologies

A Cas nuclease such as Cas9 can introduce a DNA double strand break in a sequence target that is complementary to a 20-nt spacer sequence of its bound guide RNA (gRNA) when a protospacer adjacent motif (PAM) is present. The gRNA can be provided as duplex of spacer containing CRISPR RNA (crRNA) and trans-activating crRNA (tracrRNA). Or as a single gRNA (sgRNA) where crRNA and tracrRNA are fused by an artificial loop.
Hence a gRNA consists of the target-specific spacer and a constant part typically ...

High-precision base editors for site-specific single nucleotide conversion

Ref.-No.: 0402-5782-MG

Processes and Methods (incl. Screening)

The CRISPR-Cas system is a powerful tool for site-specific genome editing. It allows for the inactivation or substitution of entire genes. However, most hereditary diseases in humans are caused by single point mutations, the correction of which requires only subtle changes to the DNA. Recently, base editors (BEs) were developed that allow the introduction of selective nucleotide substitutions. A Cas9 enzyme is fused to a nucleobase deaminase catalysing C-to-T mutations (by C-to-U deamination) ...

Proteins are the main functional units within cells. Their regulated synthesis and degradation are crucial for controlling biological processes. In all cells, protein synthesis is used to respond to extra- and/or intracellular cues to remodel cellular function. Previous studies probing the role of protein synthesis have used chemical inhibitors, often common antibiotics, which are effective but lack functional and cell-type specificity when applied to a mixture of cells.
