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 …

The discovery of hemoglobins in virtually all kingdoms of organisms has shown (1) that the
ancestral gene for hemoglobin is ancient, and (2) that hemoglobins can serve additional …

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

Mycobacterium tuberculosis, the causative agent of human tuberculosis, and Mycobacterium
bovis each express two genes, glbN and glbO, encoding distantly related truncated …

Background Globins occur in all three kingdoms of life: they can be classified into single-
domain globins and chimeric globins. The latter comprise the flavohemoglobins with a C …

In response to oxygen limitation or oxidative and nitrosative stress, bacteria express three
kinds of hemoglobin proteins: truncated hemoglobins (tr Hbs), hemoglobins (Hbs) and …

Small hemoproteins displaying amino acid sequences 20–40 residues shorter than (non-)
vertebrate hemoglobins (Hbs) have recently been identified in several pathogenic and non …

In 2000, the third member of the globin family was discovered in human and mouse brain
and named neuroglobin (Ngb). Ngb is a monomeric 3/3 globin structurally similar to …

In this study, an environment-friendly and efficient artificial Vitreoscilla hemoglobin (VHb) for
the synthesis of 2-aminobenzoxazoles and 2-aminobenzothiazoles has been reported. We …

Two putative hemoglobin genes, glbN and glbO, were recently discovered in the complete
genome sequence of Mycobacterium tuberculosis H37Rv. Here, we show that the glbN …
