Prediction structure type for human leukocyte Interferon subtype A from circular dichroism

Abstract
Vacuum UV circular dichroism studies were carried out on human leukocyte interferon subtype A. The secondary structure analysis for the CD spectrum shows 59% α‐helix, 16% antiparallel β‐sheet, no parallel β‐sheet, 18% β‐turns and 13% other structures. The analysis of the CD features for the prediction of tertiary structural class reveals that it is an all‐α type protein.
