HHsearch alignment for GI: 254780747 and conserved domain: cd07018

>cd07018 S49_SppA_67K_type Signal peptide peptidase A (SppA) 67K type, a serine protease, has catalytic Ser-Lys dyad. Signal peptide peptidase A (SppA; Peptidase S49; Protease IV) 67K type: SppA is 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. Members in this subfamily contain an amino-terminal domain in addition to the carboxyl-terminal protease domain that is conserved in all the S49 family members (sometimes referred to as 67K type), similar to E. coli and Arabidopsis thaliana SppA peptidases. Unlike the eukaryotic functional homologs that are proposed to be aspartic proteases, site-directed mutagenesis and sequence analysis have shown that members in this subfamily, mostly bacterial, are serine proteases. The predicted active site serine for members in this family occurs in a transmembrane domain. Mutagenesis studies also suggest that the catalytic center comprises a Ser-Lys
