Author Correction: The tomato subtilase family includes several cell death-related proteinases with caspase specificity

Abstract

This Article contains an error in the Methods section under subheading 'Substrate specificity of tomato phytaspases' where, "Briefly, a protein extract from Arabidopsis leaves was digested with proteomics-grade trypsin to generate a library of several thousand peptides, that were chemically modified to protect free sulfhydryl and amino groups. " should read: "Briefly, a protein extract from Arabidopsis leaves was digested with proteomics-grade chymotrypsin to generate a library of several thousand peptides, that were chemically modified to protect free sulfhydryl and amino groups. " In addition, there is an error in the legend of Figure 4 where, "Letter size reflects the relative frequency of an amino acid at a given position as compared to natural abundance in the tomato proteome. " should read: "Letter size reflects the relative frequency of an amino acid at a given position as compared to natural abundance in the Arabidopsis proteome. "
