(a) Minimal number of fluorescein molecules detected. (1) In a 200 μl well of a microtiter plate (conventional technology), (2) in 20 pl droplets27and (3) in 2 pl droplets (according to respective calibration curves;Supplementary Fig. 2). Errors bars are set to 10% of the ca...
There are many examples of oxidative enzymes containing both flavin and heme prosthetic groups that carry out the oxidation of their substrate. For the purpose of this article we have chosen five systems. Two of these, the l-lactate dehydrogenase flavocytochrome b 2 and cellobiose dehydrogenase, ...
Two examples of enzyme systems with interactions, at steady state, are treated here. In both cases, the enzyme cycle has two states and quasi-equilibrium in spatial distributions obtains at steady state (because f alpha + f beta = 1). The first example is a dilute solution of enzyme molecu...

The chapter begins with descriptions of the properties of enzymes and the principles underlying their catalytic power. Following is an introduction to enzyme kinetics, a discipline that provides much of the framework for any discussion of enzymes. Specific examples of enzyme mechanisms are then ...
(r) ≥ 0, but at the interfaces continuity is not required. The number of sub-spaces as well as the shape of the interface between each pair of sub-spaces are then also variables to be optimized (see Supplementary Note1for details and Supplementary Note2,5,6for examples). This is...

Here, we provide an overview of enzyme moonlighting in parasitic protists. Unequivocal and putative examples of moonlighting are discussed, together with the possibility that the unusual biological characteristics of some parasites either limit opportunities for moonlighting to arise or perhaps contribute ...
examples. Here, we present ESP, a general machine-learning model for the prediction of enzyme-substrate pairs with an accuracy of over 91% on independent and diverse test data. ESP can be applied successfully across widely different enzymes and a broad range of metabolites included in the ...
