but also in the laboratory. Using advanced methods such as magic-angle spinning nuclear magnetic resonance (MAS NMR) spectroscopy, they analyzed tiny ACC particles to determine their structure
Melting points were determined on an OptiMelt MPA100 apparatus (SRS, USA) without correction. FT-IR spectra were recorded on a Thermo Scientific Nicolet Summit FT-IR Spectrometer (Thermo Scientific, USA) with KBr methods in the 4000–500 cm−1range. NMR measurements were performed on a Bru...
Cyanophage S-2L is a Synechococcus phage from the double-stranded DNASiphoviridaefamily. It was first isolated and described in 197712and its genome was shown to contain no adenine nor any of its 7-deaza derivatives. Instead, it uses 2-aminoadenine (2,6-diaminopurine or Z) that has an ...
