15036292-1	2004	Neuroglobin displays a hexacoordination His-Fe-His in the absence of external ligands such as oxygen.	Histidine	40-44	neuroglobin	Homo sapiens	0-11	
15036292-7	2004	Mutation of specific cysteines, or reduction to break the S-S bond, led to a large decrease in the observed oxygen affinity of human neuroglobin, mainly due to a decrease in the histidine dissociation rate.	Histidine	178-187	neuroglobin	Homo sapiens	133-144
