hkl reflexions from crystals of native human deoxyhaemoglobin and from four isomorphous heavy-atom derivatives have been recorded photographically. The "best" phase angles have been calculated from the product of two probability functions, one derived from isomorphous replacement and the other from ...
Haemoglobin is the main transport protein present in the RBCs. It carries oxygen to all the parts of the body. Learn about the structure and functions of Haemoglobin, at BYJU’S.

cGMP Signalling in the Mammalian Brain: Role in Synaptic Plasticity and Behaviour The second messenger cyclic guanosine 3鈥 ,5鈥 -monophosphate (cGMP) plays a crucial role in the control of cardiovascular and gastrointestinal homeostastis, but its effects on neuronal functions are less established. ...
sequencing has been essential for detection of RNA species3and recent developments provided a great deal of data on polymorphisms4, expression5and half-lives6of all types of RNAs, generating a valuable resource to understand their cellular functions and regulation. Although a number of techniques ide...
Collagen has many functions: Form the structure of bones Makes up cartilage and connective tissue Prevents blood that is being pumped at high pressure from bursting the walls of arteries Is the main component of tendons, which connect skeletal muscles to bones Haemoglobin may be compared with ...
calculation if provided, as they form the outermost shell and can act as protection. In future studies, it would be worth comparing all the calculations with or without water and ligands. Here, we have performed an example comparison for the protein human oxyhaemoglobin (PDB: 1hho; Suppl. 3...

Some bacteria infecting or residing in higher organisms acquire iron from the haem (iron–porphyrin complex) of host haem-containing proteins, in particular haemoglobin in red blood cells. Most pathogenic Gram-negative bacteria transport haem across the plasma membrane using an ATP-dependent active ...
Plasmodium falciparum (Pf) relies solely on the salvage pathway for its purine nucleotide requirements, making this pathway indispensable to the parasite. Purine nucleotide levels are regulated by anabolic processes and by nucleotidases that hydrolyse th
