Abstract
Hydrogen sulfide is an environmental toxicant and gaseous neurotransmitter. It is produced enterically by sulfur-reducing bacteria and invasive pathogens including Streptococcus anginosus group, Salmonella and Citrobacter. We describe putative focal hydrogen sulfide neurotoxicity after Streptococcus constellatus meningitis, treated with adjunctive sodium nitrite and hyperbaric oxygen therapy.

Abstract
Streptococcus anginosus, an anginosus group bacterium, is frequently isolated from odontogenic abscesses, and is the oral bacterium that is primarily responsible for producing hydrogen sulfide from l-cysteine through the action of its l-cysteine desulfhydrase (βC-S lyase) enzyme. However, the relationship between its production of hydrogen sulfide and abscess formation has not been investigated. To elucidate the etiological role of hydrogen sulfide in abscess formation, we initially measured, using specific primers, expression of the lcd gene, which encodes βC-S lyase, in the pus of abscesses that formed in BALB/c mice following subcutaneous injection of S. anginosus into the dorsa. Expression of lcd was >15-fold higher when l-cysteine was present than when it was absent. A mouse virulence assay revealed that the mean diameter of abscesses caused by S. anginosus FW73 plus l-cysteine was greater than that of abscesses caused by S. anginosus FW73 in the absence of l-cysteine. These findings demonstrate that the lcd gene of S. anginosus is upregulated in mouse abscesses and that hydrogen sulfide, the product of a reaction catalyzed by βC-S lyase, plays an etiological role in odontogenic abscess formation.

Abstract
Fusobacterium nucleatum produces a large amount of the toxic metabolite hydrogen sulfide in the oral cavity. Here, we report the molecular basis of F. nucleatum H(2)S production, which is associated with two different enzymes: the previously reported Cdl (Fn1220) and the newly identified Lcd (Fn0625). SDS-PAGE analysis with activity staining revealed that crude enzyme extracts from F. nucleatum ATCC 25586 contained three major H(2)S-producing proteins. Two of the proteins with low molecular masses migrated similarly to purified Fn0625 and Fn1220. Their kinetic values suggested that Fn0625 had a lower enzymic capacity to produce H(2)S from L-cysteine (approximately 30%) than Fn1220. The Fn0625 protein degraded a variety of substrates containing betaC-S linkages to produce ammonia, pyruvate and sulfur-containing products. Unlike Fn0625, Fn1220 produced neither pyruvate nor ammonia from L-cysteine. Reversed-phase HPLC separation and mass spectrometry showed that incubation of L-cysteine with Fn1220 produced H(2)S and an uncommon amino acid, lanthionine, which is a natural constituent of the peptidoglycans of F. nucleatum ATCC 25586. In contrast, most of the sulfur-containing substrates tested, except L-cysteine, were not used by Fn1220. Real-time PCR analysis demonstrated that the fn1220 gene showed several-fold higher expression than fn0625 and housekeeping genes in exponential-phase cultures of F. nucleatum. Thus, we conclude that Fn0625 and Fn1220 produce H(2)S in distinct manners: Fn0625 carries out beta-elimination of L-cysteine to produce H(2)S, pyruvate and ammonia, whereas Fn1220 catalyses the beta-replacement of L-cysteine to produce H(2)S and lanthionine, the latter of which may be used for peptidoglycan formation in F. nucleatum.

Abstract
Hydrogen sulfide, which causes oral malodour, is generally produced from L-cysteine by the action of betaC-S lyase from oral bacteria. The betaC-S lyases from two oral bacteria, Streptococcus anginosus and S. gordonii, have been cloned, overproduced, purified and crystallized. X-ray diffraction data were collected from the two types of crystals using synchrotron radiation. The crystal of S. anginosus betaC-S lyase belonged to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 67.0, b = 111.1, c = 216.4 A, and the crystal of S. gordonii betaC-S lyase belonged to the same space group, with unit-cell parameters a = 58.0, b = 73.9. c = 187.6 A. The structures of the betaC-S lyases were solved by molecular-replacement techniques.

Abstract
Hydrogen sulfide (H2S) is a toxic gas that induces the modification and release of haemoglobin in erythrocytes; however, it also functions in methionine biosynthesis in bacteria.βC–S lyase, encoded by thelcdgene, is responsible for bacterial H2S production through the cleavage ofl-cysteine. In this study, 26 of 29 crude extracts from reference and clinical strains ofStreptococcus intermediusproduced H2S froml-cysteine. The capacities in those strains were not higher than those in strains of the other anginosus group of streptococci,Streptococcus anginosusandStreptococcus constellatus, but were much greater than those in strains ofStreptococcus gordonii, which is known to have an extremely low capacity for H2S production. Incubation of the remaining three extracts withl-cysteine did not result in H2S production. Sequence analysis revealed that thelcdgenes from these three strains (S. intermediusstrains ATCC 27335, IMU151 and IMU202) contained mutations or small deletions. H2S production in crude extracts prepared fromS. intermediusATCC 27335 was restored by repairing thelcdgene sequence in genomic DNA. The kinetic properties of the purified recombinant protein encoded by the repairedlcdgene were comparable to those of native proteins produced by H2S-producing strains, whereas the truncated protein produced byS. intermediusATCC 27335 had no enzymic activity withl-cysteine orl-cystathionine. However, real-time PCR analysis indicated that thelcdgene in strains ATCC 27335, IMU151 and IMU202 is transcribed and regulated in a manner similar to that in the H2S-producing strain.
