The peroxidase-oxidase oscillator and its constituent chemistries
Article Abstract:
The only single enzyme system that demonstrates in vitro oscillations in stirred, homogeneous solution is the peroxidase-oxidase oscillator. Medical, biological and chemical diagnostics often use peroxidase, with peroxidase generally known to act as a hydrogen peroxide scavenger. The chemistry and biochemistry of peroxidase are examined, with particular emphasis on the areas associated with chaotic and periodic oscillations. Experiments on the peroxidase-oxidase system require great care, with the influence of temperature not fully studied.

Cytochromes c': Biological models for the S=3/2, 5/2 spin-state admixture?
Article Abstract:
The electronic ground state of the ferricytochromes c' is often the subject of debate and evidence for a quantum mechanically admixed S-3/2, 5/2 ground state in these molecules is challenged. Reviews are presented of work on model heme complexes in which the properties of the S=3/2, 5/2 spin-state admixture have been established and studies related to the ground-state properties of the heme iron centers in the ferricytochromes c'.

High-resolution NMR spectroscopy of sample volumes from 1 nL to 10 micro-L
Article Abstract:
A discussion of the key developments in nuclear magnetic resonance (NMR) spectroscopy which have boosted performance for mass-limited samples is presented. It is suggested that, although the increased sensitivity of reduced-diameter radiofrequency probes gives a significant benefit for NMR spectroscopy, microcoils give a number of further benefits which have not been fully investigated.
