A natural heme deficiency exists in biology that allows nitric oxide to control heme protein functions by regulating cellular heme distribution. [PDF]
We hypothesize that tissues exist naturally in a heme‐deficient condition that limits the heme content and functions of heme proteins. The nitric oxide (NO) that is made in our tissues can control cell heme availability in a bimodal way, and so regulate heme protein functions in health and disease.

Theoretical Study on the Effective Magnetic Moments of Some Hemeproteins [PDF]
It is pointed out that the measurement of the static magnetic susceptibilities over a wide temperature range will be able to the detailed information about the electronic structure of the paramagnetic heme derivatives. On the basis of the data given by the electron paramagnetic resonance experiment, formulas for the temperature dependence of the ...

The immune function is closely related to iron (Fe) homeostasis and allostasis. The aim of this bioinformatics-assisted review was twofold; (i) to update the current knowledge of Fe metabolism and its relationship to the immune system, and (ii) to ...

Computational modelling was employed to rationally guide protein engineering toward controlling the accessible conformations of a key lactone‐carbene (LAC) intermediate in the enzyme active site by installing a new H‐bond anchoring point. This H‐bonding interaction controls the relative orientation of the fleeting carbene intermediate, orienting it for

Chemoselective Caging of Carboxyl Groups for On‐Demand Protein Activation with Small Molecules
The caging of amino acid side chains can provide exquisite control of protein function. The first chemical caging of carboxyl groups (Asp and Glu) in enzymic active sites is reported. Caging of a heme propionate in a protein was also feasible by this approach based on esterification with a tuned diazo compound.

Recent Development of the Molecular and Cellular Mechanisms of Hydrogen Sulfide Gasotransmitter
Hydrogen sulfide has been recently identified as the third biological gasotransmitter, along with the more well studied nitric oxide (NO) and carbon monoxide (CO). Intensive studies on its potential as a therapeutic agent for cardiovascular, inflammatory,

Nitrobindins (Nbs) are all-β-barrel heme proteins and are present in prokaryotes and eukaryotes. Although their function(s) is still obscure, Nbs trap NO and inactivate peroxynitrite.

Recent Approaches for Manipulating Globin Gene Expression in Treating Hemoglobinopathies
Tissue oxygenation throughout life depends on the activity of hemoglobin (Hb) one of the hemeproteins that binds oxygen in the lungs and secures its delivery throughout the body.

Rhabdomyolysis as cause, consequence, or mimicker of myocardial infarction: A case report
Key Clinical Message A timely diagnosis is essential to start appropriate therapy and to reduce risks of life‐threatening complications of rhabdomyolysis. Some cases can undergo differential diagnosis with other clinical conditions, e.g., myocardial infarction.

This study focuses on the molecular action of two histone chaperones: SET/template‐activating factor‐Iβ and nucleophosmin 1. It is shown how these chaperones have specificity for fully dismantled nucleosomes, characterized the histone eviction (removal) process, and its modulation by cytochrome c.
