Measurement of enzyme activities

Abstract

The determination of enzyme activities in organ or organellar extracts is an important means of investigating metabolic networks and allows testing the success of enzyme-targeted genetic engineering. It also delivers information on intrinsic enzyme parameters such as kinetic properties or impact of effector molecules. This chapter provides protocols on how to assess activities of the enzymes of the core photorespiratory pathway, from 2-phosphoglycolate phosphatase to glycerate 3-kinase.
