Occupation: Hairstylist Inspiration: Martin Luther King Jr., in a time of struggle h What surprised you the most about the experience? (2008). We won that one, too. In this way, the PAPS generated by the PAPSS1 enzyme from ATP and inorganic sulfate can be used in situ by the C4ST-1 enzyme to perform the sulfation of chondroitin in a single step without the need for purification of the reaction intermediates. The molar absorptivity of NADH at 340 nm has been determined by an indirect procedure in which high-purity glucose is phosphorylated by ATP in the presence of hexokinase, coupled to oxidation of the glucose-6-phosphate by NAD+ in the presence of glucose-6-phosphate dehydrogenase. For the regioselective sulfation of chondroitin, a biocatalytic cascade was developed that allows PAPS to be obtained in situ from ATP and inorganic sulfate, greatly facilitating and lowers the cost of the process. I was just thinking, I am gonna punch her in the throat! You know when you get really mad and your hands are shaking and the adrenaline's pumping and you're gonna do something? So I separated myself from the situation. 240 260 280 300 320 340 Wavelength (nm) Molar absorbance (L mol 1 cm 1) Absorbance difference (L mol 1 cm 1) (a) (b) ring in NADH shows an absorbance maximum near 340nm (e 34056220Lmol 21cm21), which is lost upon oxidation For PAPSS1 enzyme expression, preinocula of recombinant colonies were prepared in 5ml LB medium containing 30g/ml kanamycin and incubated overnight at 37C with shaking (160rpm).
