Clostridial iron-sulphur proteins.
Iron-sulfur proteins are ubiquitous catalysts of a wide range of biological reactions, and are particularly abundant in clostridia which lack the ability to synthesize hemes. The development of research on these metalloproteins has therefore been strongly associated with biochemical investigations of clostridial metabolism. Major breakthroughs in the field, from the first isolation of an iron-s...

Iron Sulphur Proteins, Volume 3
On the positive side, the concept of this series seeks to fill a genuine gap in the present literature with clear, straightforward, detailed and up-to-date accounts of the theory behind the many separation techniques currently available to biochemists. The extent to which it succeeds depends, not only on the quality of the individual contributors, but also on skilful editing. Catsimpoolas can b...
متن کاملSulphur and iron abundances in halo stars
From equivalent widths of the S i lines at 8694 Å, Israelian & Rebolo (2001) and Takada-Hidai et al. (2002) have derived a surprisingly high sulphur-to-iron ratio ([S/Fe] ≃ 0.5 to 0.7) in six halo stars with [Fe/H] ≃ −2.0 suggesting perhaps that hypernovae made a significant contribution to the formation of elements in the early Galaxy. To investigate this problem we have used high-resolution s...
