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.

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

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.

Mechanisms of Neuronal Damage in Acute Hepatic Porphyrias
Porphyrias are a group of congenital and acquired diseases caused by an enzymatic impairment in the biosynthesis of heme. Depending on the specific enzyme involved, different types of porphyrias (i.e., chronic vs. acute, cutaneous vs.

Hydrogen Sulfide and Hemeproteins: Knowledge and Mysteries [PDF]
Historically, hydrogen sulfide (H(2)S) has been regarded as a poisonous gas, with a wide spectrum of toxic effects. However, like ·NO and CO, H(2)S is now referred to as a signaling gas involved in numerous physiological processes. The list of reports highlighting the physiological effects of H(2)S is rapidly expanding and several drug candidates are ...

Hypoxic Regulation of the Large-Conductance, Calcium and Voltage-Activated Potassium Channel, BK
Hypoxia is a condition characterized by a reduction of cellular oxygen levels derived from alterations in oxygen balance. Hypoxic events trigger changes in cell-signaling cascades, oxidative stress, activation of pro-inflammatory molecules, and growth ...

Encapsulation of sugar beet phytoglobin BvPgb 1.2 and myoglobin in a lipid sponge phase system
Globins are usually associated with oxygen carriage in vertebrates. However, plants also contain similar heme-containing proteins, called phytoglobins (Pgbs).
