ChiraKit

ChiraKit processes raw circular dichroism (CD) spectroscopy data and performs advanced analysis of chiral molecules including proteins and nucleic acids.

Key Features:

• Protein Secondary Structure Calculation: Calculates protein secondary structure using the SELCON3 and SESCA algorithms.
• Peptide Helicity Estimation: Estimates peptide helicity using the helix-ensemble model.
• Unfolding Model Fitting: Fits thermal unfolding, chemical unfolding, or user-defined models.
• Spectral Decomposition: Decomposes spectra through singular value decomposition (SVD) or principal component analysis (PCA).

Scientific Applications:

• Protein Conformational Analysis: Investigates protein secondary structure, folding, and conformational changes under varying experimental conditions.
• Nucleic Acid Structure Studies: Analyzes folding and structural properties of nucleic acids using CD spectroscopy.
• Peptide Helix Quantification: Quantifies helical content in peptides through ensemble modeling approaches.
• Biomolecular Stability Assessment: Characterizes thermal and chemical stability of biomolecules through unfolding analysis.

Methodology:

ChiraKit processes raw CD data and applies SELCON3 and SESCA algorithms for secondary structure calculation, the helix-ensemble model for peptide helicity estimation, and SVD or PCA for spectral decomposition.
