ncSPC

Description

ncSPC is a program that calculates the structural propensities for folded and (intrinsically) disordered proteins from NMR chemical shift data. The program then calculates the extent of alpha-helical and beta-strand formed at each residue in the sequence. The program uses random coil reference data from ncIDP (Tamiola K, Acar B, Mulder FA. J Am Chem Soc. 2010 Dec 29;132(51):18000-3) and an algorithm for converting the measured data into secondary structure propensities (Marsh JA, Singh VK, Jia Z, Forman-Kay JD. Protein Sci. 2006 Dec;15(12):2795-804). Taking neighbor corrections into account significantly increases the accuracy of the method, hence the abbreviation ‘nc’ at the beginning of its name.
