Project description:In this study, we identified the O-glycosylation sites in recombinant Clostridium botulinum flagellin (CbFla) and Geobacillus kaustophilus flagellins, GkFlaA1 and GkFlaA2, expressed from the E. coli strains, EV136 and EV240 (K1:K12 strains engineered by Prof. Eric Vimr’s group to accumulate CMP-sialic acid in the cytosol), EV36 (wildtype K1:K12 strain), and BL21(DE3) (laboratory strain used for protein expression using T7 RNA polymerase). The recombinant flagellins were expressed with or without co-expression of motility associated factor (Maf) (flagellin nonulosonic acid glycosyltransferase) in these strains, purified and subjected to MS/MS analysis at Taplin Biological Mass Spectrometry facility.
Project description:Here we present a genome-scale metabolic model iMK1321 for Geobacillus icigianus constructed using an auto-generating pipeline with consequent thorough manual curation. The model contains 1321 genes and includes 1676 reactions and 1589 metabolites, representing the most-complete and publicly available model of the genus Geobacillus.
