From: Nano-electrospray tandem mass spectrometric analysis of the acetylation state of histones H3 and H4 in stationary phase in Saccharomyces cerevisiae

Figure 4

K9 and K14 of histone H3 are not detectably acetylated in stationary phase. A tryptic digest of histone H3 isolated from stationary phase yeast cells was analyzed by MS. The enhanced precursor ion spectrum (A) and CID fragmentation spectrum of the peptide that resolved at m/z 450.5, indicated by the asterisk in panel A, is shown (B). The partial y-ion and b-ion series visible in the fragmentation spectrum are indicated, and the b60 ion, shifted by 42-18 Da relative to b5, is indicated by an asterisk. The full m/z list of observed and predicted fragments are given in Table 4.
