IUCr) Facing the phase problem
A calcium ion has a peak height of 47σ and the sulfur peaks range from 9.6σ to 18.9σ. The peaks from calcium (Ca2+) and sulfate ... anomalous signal from sulfur as a function of energy and thickness. The red line shows the ridge of maximal signal in this ... even the sulfur signal at the Se K edge (f′′ = 0.235 electrons) can suffice. Thus, we now use sulfur SAD phasing of trypsin at ... The absorption edges of lighter elements (Z , 26; for example phosphorus, sulfur, potassium, calcium and manganese) and some ...
IUCr) Correlative vibrational spectroscopy and 2D X-ray diffraction to probe the mineralization of bone in phosphate-deficient...
Each spectrum was collected for 30 s and integrated ten times to obtain adequate signal-to-noise ratios for data analysis. An ... These changes become more evident in bone during conditions of high calcium demand, such as pregnancy or lactation, during ... and misalignment of the apatite crystals that can be related to changes in remodelling rates associated with different calcium ... which bone remodelling increases to meet increasing calcium demand (Macica et al., 2016. ). ...
IUCr) Crystal structure of the putative cyclase IdmH from the indanomycin nonribosomal peptide synthase/polyketide synthase
This method links each assigned free resonance to the signal in the bound spectrum that has moved the least from the position ... giving the crystals used for data collection in 0.2 M calcium acetate, 0.1 M MES pH 5.5, 18.6%(w/v) polyethylene glycol 8000. ...
