Miniaturized Digestion and Extraction of Surface Proteins from Candida albicans following Treatment with Histatin 5 for Mass Spectrometry Analysis

Table 2

Proteins identified from a miniaturized assay of HTN5 treatment of C. albicans with increased MS signals. Average MS signals and their standard deviations were calculated based on six replicates. Proteins indicated with an asterisk () have been determined using their associated protein families. Lower case letters in amino acid sequences indicated modified residues. Blank spaces indicated proteins unidentified by the databases.
