Protein engineering in haemoglobin

Haemoglobin Engineering: For fun and money

The recent transplantation of an unusual allosteric effect from crocodile to human haemoglobin has implications for both molecular evolution and the engineering of artificial blood substitutes.

AHSP (α-haemoglobin-stabilizing protein) stabilizes apo-α-haemoglobin in a partially folded state.

To produce functional Hb (haemoglobin), nascent α-globin (αo) and β-globin (βo) chains must each bind a single haem molecule (to form αh and βh) and interact together to form heterodimers. The precise sequence of binding events is unknown, and it has been suggested that additional factors might enhance the efficiency of Hb folding. AHSP (α-haemoglobin-stabilizing protein) has been shown previou...

Nanocomposite Based on Albumin Protein and Review of Its Applications in Medical Engineering

Albumin is a protein macromolecule that it has been attractive since the early 20th century and has several therapeutic applications. Albumin is an aboundant serum with good biocompatibility, hematopoiesis and biodegradability in blood. The existence of multiple functional groups makes it possible to carry significant amounts of therapeutic and diagnostic factors, as well as targeting factors. ...

Protein engineering.

The prospects for protein engineering, including the roles of x-ray crystallography, chemical synthesis of DNA, and computer modelling of protein structure and folding, are discussed. It is now possible to attempt to modify many different properties of proteins by combining information on crystal structure and protein chemistry with artificial gene synthesis. Such techniques offer the potential...
