Histidine decarboxylase (HDC) from Lactobacillus 30a forms a trimer around a central cavity or well. Three active sites are formed around the well at the interface of each of two adjacent molecules. HDC exhibits cooperative kinetics at pH 7.6 and can be described in terms of a two-state, T and R, model. At pH 4.8, protons stabilize HDC in the R form. Asp(More)
Ahsfrucf -Grid oscillators are an attractive way of obtaining high power levels from solid-state devices, since potentially the output powers of thousands of individual devices can be combined. The active devices do not require an external locking signal and the power combining is done in free space. In this work, 36 transistors are mounted on parallel(More)
