The inside cover picture shows a peptide array screen for transglutaminase (TG) substrates. The fluorescence spot intensities reflect the extent of crosslinking of a solute fluorescent acyl acceptor with an immobilized acyl donor. The tripeptide PQY is labeled, whereas YQP is not accepted as a substrate by microbial TG. For more details see the article by M. Pietzsch et al. on p. 1169 ff.

封面图片

内封面图片显示了用于转谷氨酰胺酶（TG）底物的肽阵列筛选。荧光点强度反映了溶质荧光酰基受体与固定的酰基供体的交联程度。三肽PQY被标记，而微生物TG不接受YQP作为底物。有关更多详细信息，请参见M. Pietzsch等的文章。在第 1169及以后
