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 …

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

An earlier stoichiometric analysis of oxygen‐limited metabolism of Escherichia coli
expressing cloned Vitreoscilla hemoglobin (VHb) suggested improved efficiency of ATP …

Since its first use in 1990 to enhance production of α-amylase in E. coli, engineering of
heterologous hosts to express the hemoglobin from the bacterium Vitreoscilla (VHb) has …

We have previously cloned the Vitreoscilla hemoglobin gene (VHb) and expressed the
protein in Escherichia coli in its active form. Under oxygen-limited conditions the presence of …

Nitric oxide (NO), generated in large amounts within the macrophages, controls and restricts
the growth of internalized human pathogen, Mycobacterium tuberculosis H37Rv. The …

The obligate aerobic bacterium, Vitreoscilla, synthesizes elevated quantities of a
homodimeric hemoglobin (VHb) under hypoxic growth conditions. Expression of VHb in …

The global human population is constantly increasing whereas the agricultural land
resources are declining for reasons of urban settlements and industrial growth. This has …

Two Escherichia coli mutants that lack both cytochrome o and d terminal oxidases are able
to grow with glucose as the carbon source but not with the aerobic substrates succinate or …

The hemoglobin of yeast is a two-domain protein with both heme and flavin prosthetic
groups. The nucleotide sequences of the cDNA and genomic DNA encoding the protein …
