Chain A,B,C   (SQHC_ALIAD | P33247)
molecular function
    GO:0016866    intramolecular transferase activity    Catalysis of the transfer of a functional group from one position to another within a single molecule.
    GO:0016853    isomerase activity    Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5.
    GO:0016829    lyase activity    Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
    GO:0051007    squalene-hopene cyclase activity    Catalysis of the reaction: squalene = hop-22(29)-ene.
biological process
    GO:0019746    hopanoid biosynthetic process    The chemical reactions and pathways resulting in the formation of hopanoids, pentacyclic sterol-like compounds based on the hopane nucleus.
cellular component
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
