>cd07014 S49_SppA Signal peptide peptidase A. Signal peptide peptidase A (SppA; Peptidase S49; Protease IV): SppA is an intramembrane enzyme found in all three domains of life and is involved in the cleavage of signal peptides after their removal from the precursor proteins by signal peptidases. Unlike the eukaryotic functional homologs that are proposed to be aspartic proteases, site-directed mutagenesis and sequence analysis have shown these bacterial, archaeal and thylakoid SppAs to be ClpP-like serine proteases. The predicted active site serine for members in this family occurs in a transmembrane domain, cleaving peptide bonds in the plane of the lipid bilayer. Mutagenesis studies also suggest that the catalytic center comprises a Ser-Lys dyad (both residues absolutely conserved within bacteria, chloroplast and mitochondrial signal peptidase family members) and not the usual Ser-His-Asp catalytic triad found in the majority of serine proteases. In addition to the carboxyl-terminal p
