De novo phasing of two crystal forms of tryparedoxin II using the anomalous scattering from S atoms: a combination of small signal and medium resolution reveals this to be a general tool for solving protein crystal structures

The structures of two crystal forms of tryparedoxin II from C. fasciculata have been determined de novo by exploiting the anomalous scattering at 1.77 Å wavelength of the S atoms in the native protein.

The crystal and molecular structures of diferric porcine and rabbit serum transferrins at resolutions of 2.15 and 2.60 Å, respectively

The X-ray structures of rabbit and porcine serum transferrins are reported at resolutions of 2.6 and 2.15 Å, respectively. The more acid-labile release of iron from serum transferrins than from lactoferrins is discussed.
