Gene : HB1 A. thaliana

Gene ID  ? AT2G16060
Brief Description  hemoglobin 1  Source: Araport11 (06/2016).
Is Obsolete?  false
Computational Description  ? hemoglobin 1 (HB1); FUNCTIONS IN: oxygen binding; INVOLVED IN: response to hypoxia; LOCATED IN: cell wall, plasma membrane; EXPRESSED IN: 22 plant structures; EXPRESSED DURING: 14 growth stages; CONTAINS InterPro DOMAIN/s: Leghaemoglobin (InterPro:IPR001032), Globin-like (InterPro:IPR009050), Leghaemoglobin, iron-binding site (InterPro:IPR019824), Globin, subset (InterPro:IPR000971), Globin (InterPro:IPR012292); BEST Arabidopsis thaliana protein match is: haemoglobin 2 (TAIR:AT3G10520.1).  Source: TAIR, Jun 30, 2015.
Curator Summary  ? Encodes a class 1 nonsymbiotic hemoglobin induced by low oxygen levels with very high oxygen affinity. It is not likely to be a hemoglobin transporter because of its extremely high affinity for oxygen. Overexpression impairs cold stress-induced nitric oxide (NO) production.  Source: TAIR, Jun 30, 2015.

Annotation PubMed Id
The structures of AHb1 and AHb2, modeled on the basis of the homologous rice hemoglobin, exhibit a different cavity system that is fully compatible with the observed ligand binding kinetics 17298064
Finding strongly supports the idea that AHb1 and AHb2 have distinct physiological functions. 17555890
the nature and distribution of internal cavities in the protein matrix 19954242
Rebinding of NO ligands was observed only from site B of AHb1, regardless of conformation. 20666470
AtHb1 overexpression led to several alterations in transcriptional and metabolic networks, resulting in improved seed yield. 21406103
Findings provide evidence supporting the functional implications of the conformational rearrangement found for the distal histidine in AHb1, which mimics the gating role proposed for the same residue in myoglobin. 21428382
