The TenA protein family occurs in prokaryotes, plants and fungi; it has two subfamilies, one (TenA_C) having an active-site cysteine, the other (TenA_E) not. TenA_C proteins participate in thiamin salvage by hydrolysing the thiamin breakdown product amino-HMP (4-amino-5-aminomethyl-2-methylpyrimidine) to HMP (4-amino-5-hydroxymethyl-2-methylpyrimidine); the function of TenA_E proteins is unknown. In this paper, Andrew Hanson and colleagues present results which indicate that TenA_E proteins mediate amidohydrolase and aminohydrolase steps in the salvage of thiamin breakdown products; considering that such products can be toxic, TenA_E proteins may also pre-empt toxicity.
ent-Kaurene is a key intermediate in the biosynthesis of the plant hormone gibberellin. In order to gain further insights into the functional diversity of ent-Kaurene biosynthetic enzymes in land plants, in this paper Hiroshi Kawaide and colleagues have analysed the function of monofunctional diterpene cyclases in Selaginella moellendorffii. Their investigation of the substrate specificity of ent-Kaurene synthases of non-flowering and flowering plants suggests that monofunctional diterpene cyclases involved in ent-Kaurene biosynthesis may have co-evolved with gibberellin biosynthesis.
GSTs (glutathione transferases) represent a superfamily of multifunctional proteins which play crucial roles in detoxification processes and secondary metabolism. Members of the Lambda class (GSTLs) are unusual in that they catalyse deglutathionylation reactions via a catalytic cysteine residue. In this paper, Arnaud Hecker and colleagues have utilized X-ray crystallography to show that GSTL1 and GSTL3 structures from Populus trichocarpa (poplar) to show that, although these proteins adopt a canonical GST fold quite similar to that found in dimeric Omega GSTs (their non-plant counterparts), they are strictly monomeric enzymes constituting an early divergent class specific to terrestrial plants.
In their exploration of G-protein-mediated signalling pathways in soya bean (Glycine max), Sona Pandey and colleagues show how subtle biochemical differences observed among recently duplicated and highly conserved Gα proteins of soya bean are functionally significant, as observed by in vivo complementation of a yeast gpa1 mutant in the pheromone-response pathway.
