In biology textbooks and beyond, the human genome and DNA therein typically are taught in only one dimension. While it can be ...

Mitochondria are cell organelles surrounded by a double membrane. In addition to numerous essential functions in the ...

Hemoglobin is known to be a source of peptides involved in several functions. The peptide FLSFPTTKTYFPHFDLSHGSAQVKGHGAK (Hb33−61) is a proteolytic product of the bovine hemoglobin α-chain found in the ...

The structure showed 12 transmembrane helices in two pseudo-symmetric bundles and two periplasmic subdomains. Experiments showed that the coiled-coil domain, whose predicted model extends from one of ...

The human pathogen Staphylococcus aureus acquires heme iron from hemoglobin (Hb) via the action of a series of iron-regulated surface determinant (Isd) proteins. The cell wall anchored IsdB protein is ...

Researchers made small tweaks to the molecular structure of LSD to see if it could be turned into an effective brain-healing treatment.

Scientists have found a way to more than double the uptake ability of a chemical structure that can be used for scrubbing carbon dioxide from factory flues.

Bizarre Scheme. Perutz studied molecular structure by analyzing X-ray photographs of crystallized hemoglobin. Scattered and deflected by the atoms within, the X-rays form a pattern of light and ...

To a molecular biologist the problem of understanding the ligand-binding function of a protein, for example, may be solved once the binding site has been identified in the three-dimensional structure.

Two researchers say that Rosalind Franklin knowingly collaborated with James Watson and Francis Crick to discover the molecular structure of DNA.
