25497832-2	2015	The protein sequence of yellow catfish SCD1 and Fads2 (Delta6) possessed all the characteristics of microsomal fatty acid Fads2 (Delta6), including three histidine boxes, two transmembrane regions and one N-terminal cytochrome b5 domain containing heme-binding motif.	Histidine	154-163	fatty acid desaturase 2	Homo sapiens	48-53	
33751430-1	2021	Here we describe a protocol for a one-step purification of a soluble form of human FAD synthase (isoform 2; hFADS2), overexpressed as a 6-His-tagged fusion protein in Escherichia coli, with a yield of about 15 mg from 1 L of transformed bacterial culture.Following a desalting procedure, the protein is obtained in its FAD-bound form (about 0.8 molecules of FAD per 1 protein monomer).	Histidine	138-141	fatty acid desaturase 2	Homo sapiens	108-114	
24101560-7	2014	The conserved region of Delta6-fatty acid desaturase included three conserved histidine-rich domain, hydropathy profile, and was rich in disulfide bonds.	Histidine	78-87	fatty acid desaturase 2	Homo sapiens	30-52	
10517856-0	1999	Histidine-41 of the cytochrome b5 domain of the borage delta6 fatty acid desaturase is essential for enzyme activity.	Histidine	0-9	fatty acid desaturase 2	Homo sapiens	55-83
