GE37468 mutants and impacts on PTM processing. The 12 active variants indentified in the overlay assay are listed in green. Inactive mutants found in MALDI-TOF assay, but not in the overlay assay, are listed in black. An asterisk indicates downstream processing is affected in the dominant product. No mutants were tolerated at residue 4. See also Figures S3b–gg, 4a.
