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 …

The activation of dioxygen (O 2) by metalloenzymes proceeds by binding O 2 at their active
sites and then generating highly reactive, thermally unstable metal-oxygen intermediates …

Several molecular dynamics (MD) simulations were used to sample conformations in the
neighborhood of the native structure of holo-myoglobin (holo-Mb), collecting trajectories …

A half century ago, Max Perutz and John Kendrew determined the crystal structure of two
heme-containing proteins: hemoglobin and myoglobin, respectively. 1, 2 These landmark …

Covering: up to July 2008 A discussion of the literature concerning the synthesis, function,
and activity of hemec-containing proteins is presented. Comparison of the properties of …

The heme prosthetic group in hemoglobins is most often attached to the globin through
coordination of either one or two histidine side chains. Those proteins with one histidine …

Plant hemoglobins constitute a diverse group of hemeproteins and evolutionarily belong to
three different classes. Class 1 hemoglobins possess an extremely high affinity to oxygen …

Plants express three phylogenetic classes of hemoglobins (Hb) based on sequence
analyses. Class 1 and 2 Hbs are full‐length globins with the classical eight helix Mb‐like …

Globins (Glbs) are widely distributed in archaea, bacteria and eukaryotes. They can be
classified into proteins with 2/2 or 3/3 α‐helical folding around the heme cavity. Both types of …

Legume nodules have two types of hemoglobins: symbiotic or leghemoglobins (Lbs) and
nonsymbiotic or phytoglobins (Glbs). The latter are categorized into three phylogenetic …
