13. Myristate-protein interactions in poliovirus: interactions of VP4 threonine 28 contribute to the structural conformation of assembly intermediates and the stability of assembled virions.
The VP4 capsid protein of poliovirus is N-terminally modified with myristic acid. Within the poliovirus structure, a hydrogen bond is observed between the myristate carbonyl and the hydroxyl side chain of threonine 28 of VP4. This interaction is between two fivefold symmetry-related copies of VP4 and is one of several myristoyl-mediated interactions that app

14. Photoacoustic analysis of proteins: volumetric signals and fluorescence quantum yields.
A series of proteins has been examined using time-resolved, pulsed-laser volumetric photoacoustic spectroscopy. Photoacoustic waveforms were collected to measure heat release for calculation of fluorescence quantum yields, and to explore the possibility of photoinduced nonthermal volume changes occurring in these protein samples. The proteins studied were th

15. Effects of Temperature on Activation, Germination, and Outgrowth of Bacillus megaterium Spores1
The effects of temperature on the activation, glucose-induced germination, and outgrowth of Bacillus megaterium QM B1551 spores were investigated. There was no evidence for discontinuities in the response of spores to temperature in these processes reflecting reported thermal anomalies in the physical structure of water. Increasing the temperature of heat ac
