30604098-2	2019	All insulin superfamily members contain three absolutely conserved disulfide linkages and a nonchiral Gly residue immediately following the first B-chain cysteine.	Glycine	102-105	insulin	Homo sapiens	4-11	
30604098-3	2019	The functionality of this conserved Gly residue in the insulin family has been studied by replacing it with natural L-amino acids or the corresponding unnatural D-amino acids.	Glycine	36-39	insulin	Homo sapiens	55-62	
30604098-8	2019	The present study revealed functionality of the conserved B-chain Gly residue for a relaxin family peptide for the first time, providing an overview of its contribution to foldability and activity of the insulin superfamily.	Glycine	66-69	insulin	Homo sapiens	204-211
