Determining the structural stability of UiO-67 with respect to time: a solid-state NMR investigation
Publikováno v:
Chemical Communications. 52:4971-4974
The stability of UiO-67 has been questioned for some time. We have used solid-state NMR to investigate the temporal stability of this MOF. Proper activation is necessary to achieve optimal surface area. However, even with proper activation, the long-

An engineered fusion protein containing two tandem lactose permease molecules (permease dimer) exhibits high transport activity and is used to test the phenomenon of negative dominance. Introduction of the mutation Glu-325-->Cys into either the first

Binding specificity in lactose permease toward galactopyranosides is governed by H-bonding interactions at C-2, C-3, C-4, and C-6 OH groups, while binding affinity can be increased dramatically by nonspecific hydrophobic interactions with the non-gal

The sucrose (CscB) permease belongs to the oligosaccharide:H(+) symporter family of the Major Facilitator Superfamily and is homologous to the lactose permease from Escherichia coli. Sucrose transport in cells expressing sucrose permease is completel

We describe here a sub-family of enzymes related both structurally and functionally to N-acetylneuraminate lyase. Two members of this family (N-acetylneuraminate lyase and dihydrodipicolinate synthase) have known three-dimensional structures and we n

The neutron inelastic scattering and infrared absorption spectra of chromous acid are analyzed using a double Morse potential model. The proton tunneling frequency is assigned to a peak at 548 cm−1 and the ‖0〉→‖2〉 transition to the band a

We have matched the red absorption band measured at −196 C in a variety of chloroplast preparations with four major component curves representing forms of chlorophyll a having peaks at 661.6, 669.6, 677.1, and 683.7 nanometers. Chloroplast fraction
