NICE system

In the example in the preceding section, one of the equations in the system of equations had a convenient relationship. The equation c = 2r allowed for a quick substitution back into the other two equations, creating a nice system... 

Yamamoto et al. developed a nice system by which the redox units within a... 

Bevan It is a rather nice system where there are opposite effects in the same cell by activating the same pathways. 

Finally, this linear problem is only important to us because it can be connected to the solution of the full nonlinear problem. Although precise statements of this connection require more mathematics than we can assume, the general result may be summed up for "nice systems... 

Lindhorst had proposed a nice system of two complementaiy ABa-type carbohydrate building blocks, both allow a wide set of further modifications on their orthogonal functional groups. The block synthesis relies on the selective modification of two positions in a selected monosaccharide the anomeric position and the primary hydroxyl group. 

Nisin-controlled gene expression (NICE) The NICE system is the most commonly used inducible expression system for heterologous proteins production in LAB. The synthesis. 

More recently, a new zinc-inducible expression system, called Zirex, was developed for L. Metis (Mu et al. 2013). When triggered by a non-toxic concentration of zinc, the streptococcal promoter PczcD (regulated by the SezA repressor) is activated and leads to elevated expression levels. Moreover, Mu and colleagues have successfully combined both the NICE system and Zirex to produce different proteins at different times in the same microorganism.
