A Diffusion-Based Approach to Geminate Recombination of Heme Proteins with Small Ligands [PDF]

, 2002
A model of postphotodissociative monomolecular (geminate) recombination of heme proteins with small ligands (NO, O2 or CO) is represented. The non-exponential decay with time for the probability to find a heme in unbound state is interpreted in terms of ...

Early life stress induces dysregulation of the heme pathway in adult mice

Physiological Reports, 2021
Early life stress (ELS) is associated with cardiovascular disease (CVD) risk in adulthood, but the underlying vascular mechanisms are poorly understood.

The role of peroxidase in the enzymatic oxidation of phenolic compounds to quinones from Luffa aegyptiaca (gourd) fruit juice

Green Chemistry Letters and Reviews, 2017
Luffa aegyptiaca fruit juice was used as a low purity source of enzyme, which contained peroxidase activity of 180 IU/mL. The results of UV/VIS and IR studies suggested that L.

Clinically Important Features of Porphyrin and Heme Metabolism and the Porphyrias

Metabolites, 2014
Heme, like chlorophyll, is a primordial molecule and is one of the fundamental pigments of life. Disorders of normal heme synthesis may cause human diseases, including certain anemias (X-linked sideroblastic anemias) and porphyrias.

Heme Catabolism and Heme Oxygenase in Neurodegenerative Disease

Antioxidants & Redox Signaling, 2004
Heme oxygenase, the rate-limiting step in heme catabolism, appears to play an important role in a number of neurodegenerative disorders, such as Alzheimer disease. Interestingly, the spatial distribution of heme oxygenase-1 expression in diseased brain is essentially identical to that of the pathological expression of tau, suggesting a key role for ...

Heme b (protoheme IX) is a precursor of heme a and heme d in Bacillus subtilis [PDF]

FEMS Microbiology Letters, 1993
Bacillus subtilis can synthesise cytochromes containing a-, b-, c- and d-type heme. The biosynthetic pathways of these heme prosthetic groups were investigated by using strains blocked in uroporphyrinogen III synthesis from porphobilinogen or in heme b (protoheme IX) synthesis from uroporphyrinogen III. The results strongly suggest that heme a and heme

Heme as Possible Contributing Factor in the Evolvement of Shiga-Toxin Escherichia coli Induced Hemolytic-Uremic Syndrome

Frontiers in Immunology, 2020
Shiga-toxin (Stx)-producing Escherichia coli hemolytic-uremic syndrome (STEC-HUS) is one of the most common causes of acute kidney injury in children.

Proximal and distal control for ligand binding in neuroglobin: role of the CD loop and evidence for His64 gating [PDF]

, 2019
Neuroglobin (Ngb) is predominantly expressed in neurons of the central and peripheral nervous systems and it clearly seems to be involved in neuroprotection.
