Putative thiaminase I operons in the three Paenibacillus species. Annotations of conserved genes shared amongst the three species are as follows (1) thiM; (2) thiD; (3) thiE; (4) glycosyltransferase; (5) thymidylate synthase; (6) methyltransferase; (7) yzgD NUDIX hydrolase; (8) thiaminase I and (9) HAD hydrolase. Three genes in P. apiarius B23460 that are not conserved include a putative transcriptional regulator and two genes of unknown function. The operons may be under the control of a putative thiamin pyrophosphate binding riboswitch, upstream of thiM. Genes are color-coded based on proposed functions
