For example, superoxide dismutase (Saro_0483), a tetratricopeptide repeat protein (Saro_0209), and two peptidyl-prolyl cis-trans isomerases (Saro_0837 and Saro_2251) are known to be localized in the periplasm in other Gram-negative bacteria.

(33) This is particularly interesting in that dietary trans-fat is almost entirely consumed as singly unsaturated C18 FAs, whereas C18:2 isomers are, at least to some extent, interconverted by enoyl isomerases, (22) and thus may reflect both nondietary and dietary constituents of the cell membrane FA content.
The plant GSTs, in addition to their enzymatic activities, have less well characterized roles in endogenous metabolism including functioning as GSH-dependent peroxidases counteracting oxidative stress (Bartling et al., 1993; Cummins et al., 1999; Roxas et al., 1997), or GSH-dependent isomerases (Dixon et al., 2000, Thorn et al., 2001), and noncatalytically acting as flavonoid-binding proteins (Mueller et al., 2000), stress signalling proteins (Loyall et al., 2000), regulators of apoptosis (Kampranis et al., 2000).
