Vertebrate hemoglobin (Hb) and myoglobin (Mb) were among the first proteins whose
structures and sequences were determined over 50 years ago. In the subsequent …

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 …

Abstract αβ T cell receptors (αβTCRs) co-recognise antigens when bound to Major
Histocompatibility Complex (MHC) or MHC class I-like molecules. Additionally, some …

A bioinformatics survey of putative globins in over 2200 bacterial and some 140 archaeal
genomes revealed that over half the bacterial and approximately one fifth of archaeal …

The diatomic molecules, O 2, NO and CO, have had a myriad of roles in biology. Due to this,
nature has developed many sensing proteins to perceive and respond to changes in the …

This review discusses the evolution of land plant hemoglobins within the broader context of
eukaryote hemoglobins and the three families of bacterial globins. Most eukaryote …

The PVC superphylum is a grouping of distinct phyla of the domain bacteria proposed
initially on the basis of 16S rRNA gene sequence analysis. It consists of a core of phyla …

Abstract Significance: Erythrocyte hemoglobin (Hb) and myocyte myoglobin, although
primarily oxygen-carrying proteins, have the capacity to do redox chemistry. Such redox …

The enzyme nitric oxide synthase (NOS) oxidizes L-arginine to NO and citrulline. In this
work, we characterise the NOS from the cyanobacteria Synechococcus PCC 7335 (SyNOS) …

In order to infuse hemoglobin into the vasculature as an oxygen therapeutic or blood
substitute, it is necessary to increase the size of the molecule to enhance vascular retention …
