Azanone (HNO) interaction with Hemeproteins and metalloporphyrins

2012
Abstract Azanone (HNO), also called nitroxyl, is a highly reactive compound, with interesting yet poorly understood biological properties. Like its closely related sibling NO, its main biological targets are heme proteins, although significant differences in their reactivity and pharmacological effects are observed.

Syntehsis and structural stability of helichrome as an artificial hemeproteins

Biopolymers, 1990
AbstractA detailed procedure is described for the syntehsis of helichrome, which is the first successful example of polypeptide‐based artificial hemeprotein. The segment synthesis‐condensation approach used for the assembly of small proteins has proven to be extremely useful for protein mimetics as well.

Peptide scanning in structural -functional mapping of hemeproteins

2006
Peptide scanning (PEPSCAN) is widely used for linear antigenic mapping of proteins, because it reveals almost all possible linear B-epitopes in a protein [1]. To our mind, linear antigenic determinants may have some common structural characteristics, thus allowing antigenic mapping data to be applied in structural studies of proteins.

Vibrational Circular Dichroism of Ligand Vibrations in Hemeprotein

1995
The distal amino acid residues in myoglobin (Mb) and hemoglobin (Hb) are elaborately designed to control the chemical reactions of ligands to the heme iron. Many techniques have been applied to elucidate the reaction mechanism of ligand binding in heme pockets.

Alkaline low spin form of sulfite reductase hemeprotein subunit

Biochemical and Biophysical Research Communications, 1990
The reversible reduction and reoxidation of Escherichia coli sulfite reductase hemeprotein subunit at pH 9.9 produces high and low spin ferric species, the latter with properties distinct from any alkaline low spin yet reported. With virtually no effect on the 298 degrees K optical spectrum, chloride drastically reduces the low spin EPR intensity and ...

Signal Sensing and Signal Transduction with Heme and Hemeproteins

ECS Meeting Abstracts, 2020
The heme-based sensor proteins become a new family of hemeproteins that show a new biological function as the sensor for gas molecules such as O2, CO, and NO.These gas molecules can act as signaling molecules for the regulation of biological signal transduction systems. These regulatory systems consist of a sensor and regulatory domains/proteins, in
