WebFeb 13, 2015 · Earlier kinetics studies on cytoglobin did not assign functional properties to specific structural forms. Here, we used defined monomeric and dimeric forms and cysteine mutants to show that an intramolecular disulfide bond (C38–C83) alters the dissociation rate constant of the intrinsic histidine (H81) (∼1000 fold), thus controlling binding of extrinsic … Webreducing agents to break the S–S bond, led to a decrease in the observed oxygen affinity of human neuroglobin by an order of magnitude. The critical parameter is the histidine dissociation rate, which changes by about a factor of 10. The same effect is observed with human cytoglobin, although to a much lesser extent (less than a factor of 2).

Cytoglobin is the protein product of CYGB, a human and mammalian gene. Cytoglobin is a globin molecule ubiquitously expressed in all tissues and most notably utilized in marine mammals. It was discovered in 2001 and named cytoglobin in 2002. It is thought to protect against hypoxia.
