N-Acetyl-neuraminic acid cytidylyltransferase (EC 2.7.7.43) (CMP-Neu5Ac synthetase), which catalyzes the formation of cytidine-5′-monophospho-N-acetyl-neuraminic acid (CMP-Neu5Ac) from cytidine-5′-triphosphate (CTP) and N-acetyl-neuraminic acid (Neu5Ac), was purified from rat brains aged 8–9 days, which presented the highest specific activity, and partially characterized. Partial protein fractionation...
Abstract:The first FT-Raman spectroscopic study of foliicolous lichens is reported. Detailed spectra obtained by macroscopic and microscopic means for Calenia triseptata Zahlbr., Echinoplaca strigulacea (Müll. Arg.) R.Sant. and Tricharia carnea (Müll. Arg.) R.Sant. collected from Costa Rican rainforests have been interpreted mainly in terms of their oxalate content. The Raman spectra show a significant...
