The K m of n-acetyl-β-d-glucosaminidase has been reported at values ranging from 0.096 mM in marine fungi to 0.27 mM in Aeromonas sp. for the hydrolysis of p-nitrophenyl-β-d-n-acetylglucosaminide. [ 7 ] [ 11 ] The same reaction catalyzed by proteins isolated from calf brain was generated at an observed K m of 0.72 mM, with a maximum reaction ...
The hybrid approach to constructing density functional approximations was introduced by Axel Becke in 1993. [1] Hybridization with Hartree–Fock (HF) exchange (also called exact exchange) provides a simple scheme for improving the calculation of many molecular properties, such as atomization energies, bond lengths and vibration frequencies, which tend to be poorly described with simple "ab ...
1,1-Dichlorotetrafluoroethane is a chlorofluorocarbon also known as CFC-114a or R114a by American Society of Heating, Refrigerating, and Air Conditioning Engineers. [2] It has two chlorine atoms on one carbon atom and none on the other.
The first step is cleavage of the dimer, which is W: 1 / 2 [Rh(CO) 2 Cl] 2 → Rh(CO) 2 Cl W = −10.39 kcal/mol. The second step is the binding of B to RhCl(CO) 2 monomer. In this case, W = −10.39 kcal/mol. In other cases, W is the enthalpy needed to cleave the internal hydrogen bonding of the H-bonding acid (CF 3) 3 COH. W is also ...
A more recent analysis ranked amino acids by their propensity to form disordered regions as follows (order promoting to disorder promoting): W, F, Y, I, M, L, V, N, C, T, A, G, R, D, H, Q, K, S, E, P. [49] As it can be seen from the list, small, charged, hydrophilic residues often promote disorder, while large and hydrophobic residues promote ...

Cold agglutinin disease (CAD) is a rare autoimmune disease characterized by the presence of high concentrations of circulating cold sensitive antibodies, usually IgM and autoantibodies that are also active at temperatures below 30 °C (86 °F), [1] directed against red blood cells, causing them to agglutinate and undergo lysis.
