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

Figure 5

Histone H3 K36, but not K37, is acetylated in exponential phase. A tryptic digest of histone H3 isolated from exponential phase yeast cells was analyzed by MS. The enhanced product ion spectrum (A) and CID fragmentation spectrum of the peptide that resolved at 455.6 Da, 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 b9 peak, shifted by 42 Da relative to the mass of lysine, is indicated by an asterisk. The full m/z list of observed and predicted fragments are given in Table 5.
