Nitrite is one of the players in the broad nitrogen biogeochemical cycle. This nitrogen oxo-
anion is involved in key pathways crucial to life on Earth and to the planetary “recycling” of …

Hemoglobin (Hb) occurs in all the kingdoms of living organisms. Its distribution is episodic
among the nonvertebrate groups in contrast to vertebrates. Nonvertebrate Hbs range from …

Although the compound pollution of microplastics and arsenic (As) in paddy soil can affect
the growth and quality of rice, relevant research on this phenomenon was limited. Therefore …

Neuroglobin is a recently discovered member of the globin superfamily that is suggested to
enhance the O 2 supply of the vertebrate brain. Spectral measurements with human and …

Nitric oxide (NO) is a widespread signaling molecule, and numerous targets of its action
exist in plants. Whereas the activity of NO in erythrocytes, microorganisms, and invertebrates …

We have identified a new human hemoglobin that we call histoglobin because it is
expressed in a wide array of tissues. Histoglobin shares less than 30% identity with the other …

This Handbook on Metalloproteins focuses on the available structural information of proteins
and their metal ion coordination spheres. It centers on the metal ions indispensable for life …

Neuroglobin and cytoglobin reversibly bind oxygen in competition with the distal histidine,
and the observed oxygen affinity therefore depends on the properties of both ligands. In the …

Neuroglobin, mainly expressed in vertebrate brain and retina, is a recently identified
member of the globin superfamily. Augmenting O 2 supply, neuroglobin promotes survival of …

Microbial flavohemoglobins (flavoHbs) and hemoglobins (Hbs) show large NO
dioxygenation rate constants ranging from 745 to 2900 μM− 1s− 1 suggesting a primal NO …
