Description

In bacteria, the majority of exported proteins are transported by the general Sec pathway from their site of synthesis in the cytoplasm across the cytoplasmic membrane. The ATPase SecA powers this Sec-mediated export [PMID: 23000954]. Members of this family always occur in genomes with the preprotein translocase SecA (IPR000185) and closely resemble it, hence the designation SecA2. However, this appears to be a different type of accessory Sec system SecA2 from the serine-rich glycoprotein type found in Staphylococcus and Streptococcus (IPR022490), and the actinobacterial SecA2 (IPR026389). This type occurs in species such as Bacillus anthracis, Geobacillus thermoglucosidasius, Solibacillus silvestris, etc [PMID: 22609926].
