Mass spectrometry analysis of procyclins. Butanol extracts of (A) PF 29-13, (B) TbAMPKβ, and (C) TbAMPKγ silenced cells grown in low glucose medium were dephosphorylated with aqueous HF and aliquots analyzed by MALDI-TOF-MS in positive mode. Some of the unlabelled ions in B and C correspond to fragments of EP-procyclins that lack 10 amino acids from the N-terminus (Acosta-Serrano, et al., 2000). Asterisks represent a contaminant that has been previously assigned as KMP-11 (Acosta-Serrano, et al., 1999).
