accessory Sec system translocase SecA2, Bacillus type
Members of this family always occur in genomes with the preprotein translocase SecA (TIGR00963) and closely resemble it, hence the designation SecA2. However, this appears to mark a different type of accessory Sec system SecA2 (TIGR03714) from the serine-rich glycoprotein type found in Staphylococcus and Streptococcus, and the actinobacterial SecA2 (TIGR04221). This type occurs in species including Bacillus anthracis, Geobacillus thermoglucosidasius, Solibacillus silvestris, etc. [Protein fate, Protein and peptide secretion and trafficking]
