Tant of E. coli growing under ammonium-limited conditions accumulated glutamine (12 mM) relative to the wild type (2 mM) (135). Induction of AmtB from a plasmid by IPTG (in order to increase the intracellular ammonium concentration so that GDH would be active) did not have the anticipated positive effect on growth of the gltB mutant, however (281).

Ying SNARE complex assembly and disassembly and their control by chaperones including membrane tethering factors, Sec1-Munc18 proteins (SM proteins) [G], and Nethylmaleimide-sensitive fusion factor (NSF) [G]. Membrane tethering factors8-10 not only mediate the initial contact between a vesicle and its target membrane but also bind SNAREs to regulate their assembly. Tethering factors work together
As used to dry them prior to resuspension in 5 (v/v) formic acid. Peptide concentrations were determined using the CBQCA assay after 25-fold dilution of peptide samples in 0.1 M borate buffer, pH 9.3. Denaturing Size-exclusion Chromatography--For the denaturing SEC, cells were lysed in PBS containing inhibitors as above and supplemented with 4 SDS, 25 mM TCEP, and 50 mM N-ethylmaleimide. The col
Ization of targetfocused libraries for drug discovery is typically rationalized by invoking the savings realized in screening a smaller number of compounds with a higher en mass hit rate. This scenario can be true when the focused library is tasked with providing structures that act through mechanisms (and sites) similar to those affected by the populated prototypes. But it cannot account for allo

S and shifting of the peptide signals by different RNA fragments masses are annotated and highlighted as bold letter. Proposed schematic illustration structures for peptide-RNA cross-links along with and without cross-link product of 152 Da mass are shown on the right side of each corresponding spectrum. Fragmentation of RNA refers as yr1, xr1, wr1 and yr2 by McLuckey et al. (61). E, Mapping of ML
