Many organisms contain “head-to-head” isoprenoid synthases and here, we investigate three types of such enzymes from the pathogens Neisseria meningitidis, N. gonorrhoeae, and Enterococcus hirae. The E. hirae enzyme was found to produce dehydrosqualene and we solved an inhibitor-bound structure which revealed a fold similar to that of CrtM from Staphylococcus aureus. In contrast, the homologous proteins from Neisseria spp. carried out only the “first half” reaction, yielding presqualene diphosphate (PSPP). Based on product analyses, bioinformatics, and mutagenesis we conclude that the Neisseria proteins are HpnDs (PSPP synthases). The differences in chemical reactivity to CrtM are due at least in part to the presence of a PSPP-stablizing arginine in the HpnDs, decreasing the rate of dehydrosqualene biosynthesis. These results show that not only S. aureus but also other bacterial pathogens contain “head-to-head” prenyl synthases, although their biological functions remain to be elucidated. Bacteria that cause meningitis, gonorrhea and some cases of endocarditis and septicemia all express terpene synthase-like proteins. We show that they make presqualene diphosphate or dehydrosqualene and report one X-ray structure with a bound inhibitor.
