A Test of the Role of Electrostatic Interactions in Determining the CO Stretch Frequency in Carbonmonoxymyoglobin
Electrochemistry Escherichia coli Humans Mutagenesis, Site-Directed Myoglobin Point Mutation Protein Conformation Recombinant Proteins Spectroscopy, Fourier Transform Infrared Vibration
2016/5/23
The vibrational frequency of CO bound to myoglobin can be varied by up to 60 cm-1 by making site-specific mutations in the distal pocket. These changes may result from specific chemical interactions b...

Penalized Logistic Regression for Detecting Gene Interactions
Penalized Logistic Regression Detecting Gene Interactions
2015/8/21
We propose using a variant of logistic regression with L2 regularization to fit genegene and gene-environment interaction models. Studies have shown that many common diseases are influenced by interac...
