Mass spectrum obtained for tryptic peptides eluted from 1-D gel band (51.4 kDa). After a baseline correction, a background subtraction, and peak deisotoping, 30 ions were submitted to Mascot. Twenty one of the submitted ions were matched to theoretical tryptic peptides from glutamate dehydrogenase; the sequences of these peptides are shown next to the mass of the monoisotopic, singly charged ions. The full protein sequence and the sequenced peptides are in bold
