Streptococci and corynebacteria are among the most abundant oral commensals and their interactions are critical for normal biofilm development. We have previously revealed a specifically symbiotic interaction between Streptococcus sanguinis and Corynebacterium durum via the release of C. durum fatty acids associated with membrane vesicles (MVs), enhancing bacterial fitness. Subsequently, S. sanguinis fatty acid metabolism-related genes have been studied. Glycerol dehydrogenase (gldA) was firstly characterized its essential role during the interspecies interaction. In this study, we have further characterized glycerol kinase (glpK) as another key gene being involved in S. sanguinis and C. durum interaction. In contrast to gldA, we have discovered a unique, complementary role of glpK during the interaction, in particularly, in the absence of glucose as a carbohydrate source of energy. Overall, our findings have supported the emerging role of commensal Corynebacterium spp. as major drivers of oral biofilm ecology, potentially shaping symbiotic health-associated biofilm communities. 000009540 540__ $$fCC BY 000009540 650__ $$aGlycerol Kinase$$019625 000009540 650__ $$aFatty Acids$$018911 000009540 6531_ $$amembrane vesicles 000009540 6531_ $$aoral microbiome 000009540 6531_ $$asymbiotic interaction 000009540 691__ $$aSchool of Dentistry$$041368 000009540 692__ $$aDepartment of Restorative Dentistry$$041446 000009540 7001_ $$aTreerat, June$$uOregon Health and Science University$$041354 000009540 711__ $$aResearch Week$$uOregon Health and Science University 000009540 711__ $$d2022 000009540 7201_ $$aKreth, Jens$$eCollaborator$$7Personal$$uOregon Health and Science University 000009540 7201_ $$aMerritt, Justin$$eCollaborator$$7Personal$$uOregon Health and Science University 000009540 8564_ $$9e96cab2c-e284-4a3b-ac0b-433d90601645$$s189465$$uhttps://digitalcollections.ohsu.edu/record/9540/files/Treerat-June-OHSU-ResearchWeek-2022.pdf 000009540 905__ $$a/rest/prod/63/95/w8/04/6395w8048 000009540 980__ $$aResearch Week
