(β-Asp5)-Delta-Sleep Inducing Peptide
(β-Asp5)-Delta-Sleep Inducing Peptide (DSIP-isoD) is a synthetic polypeptide that can be partially hydrolyzed by NaOH or SDS. (β-Asp5)-Delta-Sleep Inducing Peptide can be used to study the catalytic activity of mitochondrial protein L-isoaspartyl (D-aspartyl) methyltransferase (PIMT).
