Bacterial nanocellulose (BNC) produced by aerobic bacteria is a biopolymer with
sophisticated technical properties. Although the potential for economically relevant …

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

This paper presents a critical review of the literature on the application of genetically
engineered microorganisms (GEMs) in bioremediation. The important aspects of using …

Oxygen plays a key role during bacterial cellulose (BC) biosynthesis by Gluconacetobacter
xylinus. In this study, the Vitreoscilla hemoglobin (VHb)-encoding gene vgb, which has been …

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 …

Vitreoscilla hemoglobin (VHb) can enhance the ability of recombinant strains to express
heterologous proteins under low-oxygen conditions. However, its mechanism of action in the …

Flavohemoglobins (flavoHbs) are made of a globin domain fused with a ferredoxin
reductaselike FAD‐and NAD‐binding modules. These proteins are widely represented …

The x-ray structure of ferric unliganded lipid-free Escherichia coli flavohemoglobin has been
solved to a resolution of 2.2 Å and refined to anR-factor of 19%. The overall fold is similar to …

The bacterium, Vitreoscilla, can induce the synthesis of a homodimeric hemoglobin under
hypoxic conditions. Expression of VHb in heterologous bacteria often enhances growth and …

Members of the hemoglobin superfamily efficiently catalyze nitric‐oxide dioxygenation, and
when paired with native electron donors, function as NO dioxygenases (NODs). Indeed, the …
