Identification of 'erasers' for lysine crotonylated

Most of the DNA in a cell is wound around histone proteins to form a compacted structure called chromatin. Enzymes can modify the histones by adding small chemical tags on to them, and these histone modifications can cause the chromatin to either become more tightly packed or more open. Opening up the chromatin makes the DNA more accessible to the cellular machinery Get price

Arabidopsis V

The productivity of higher plants as a major source of food and energy is linked to their ability to buffer changes in the concentrations of essential and toxic ions. Transport across the tonoplast is energized by two proton pumps, the vacuolar H+-ATPase (V-ATPase) and the vacuolar H+-pyrophosphatase (V-PPase); however, their functional relation and relative contributions to ion Get price

Why the ball to powder ratio (BPR) is insufficient for

The ball to powder ratio (BPR) is a processing parameter that is frequently used in both mechanical (ball) milling and mechanical alloying. A number of recent studies provided the BPR as a principal milling parameter while neglecting other parameters, such the vial volume, the diameter and quantity of milling balls and the powder mass.Get price
