AbstractUpon N-stepdown, Anabaena sp. PCC 7120 differentiates heterocysts along filaments in a semiregular pattern. A 17-amino acid peptide called PatS is a morphogen precursor for pattern formation. The principal PatS derivative involved in heterocyst patterning has been proposed to be the C-terminal peptide PatS-5 (RGSGR), PatS-6 (ERGSGR), or PatS-8 (CDERGSGR). We present the first evidence for processing of PatS in cell extracts of this cyanobacterium. PatS is probably cleaved between the C-terminal 7th and 8th amino acid residues, producing PatS-7 (DERGSGR), then converted into PatS-6 and PatS-5. The processing site could be changed by a substitution at the C-terminal 8th residue.
