Suc-ALPF-pNA is a colorimetric substrate for peptidyl prolyl cis-trans isomerases (PPIases) including FK-506 binding proteins (FKBPs, also called macrophilins) and cyclophilins. PPIases, or rotamases, catalyze the cis-trans isomerisation of proline imidic peptide bonds to accelerate protein folding.

Activity is quantified by the release of p-nitroaniline which is measured by absorbance at 405 nm.
