BCX-a xylanase from Bacillus cirulans What’s a xylanase? How would you isolate it?
Enzymatic plant cell wall degradation occurs in a wide variety of processes. Firstly, in planta, the enzymatic modification of the cell wall is required for both cell expansion and for developmental events. Secondly, in order to invade a plant host, microorganisms are armed with a deconstructing cocktail of enzymes that depolymerize polysaccharides in the plant cell wall. And thirdly, cell wall degradation is a key process in many industrial applications and in the utilization of plant biomass.

The lac operon • E-coli uses three enzymes to take up and metabolize lactose. • The genes that code for these three enzymes are clustered on a single operon – the lac Operon. What’s lactose??
