PME17 and SBT3.5 proteins are identified in cell-wall-enriched 10-d-old root protein extracts. Structural domains (top) and amino acid sequences with peptides identified by MS (bottom) are shown for PME17 (A) and SBT3.five (B). On the structural domains, numbers indicate amino acids in the catalytic site, based on numbering of crystalized models, and domain boundaries. On the amino acid sequences, peptides identified by MS are underlined. Residues involved in catalysis are highlighted in yellow and putative N-glycosylation web pages are coloured in pink and dotted underlined. Within the PME17 sequence, the putative simple processing motif RKLL is highlighted in black.Kazal family members of serine protease inhibitors (Tian and Kamoun, 2005). Following apoplastic washes, equal amounts of extracted proteins were resolved by SDS AGE (Fig. 6B), transferred to nitrocellulose membrane and probed with anti-c-Myc antibodies (Fig. 6C). Within the absence of SBT3.five, two bands inside a molecular mass selection of 35?8 kDa were detected in the apoplasm (Fig. 6C). This suggests that, even though a single RKLL sequence was identified, two processing motifs might be present in thePME17 amino acid sequence, each of that are cleaved by an endogenous tobacco subtilase/protease. An additional band at a molecular mass close to 61 kDa most likely represents the nonprocessed kind of PME17. The recovery of this non-processed form in apoplastic washes is probably to become explained by a slight contamination (5 ) with cytosolic content, as measured by way of an a-mannosidase enzymatic assay (Supplementary Data Table S4).
