   3.2.1.B3 | beta-D-fructofuranosyl 6-O-phosphono-alpha-D-glucopyranoside + H2O |
i.e. sucrose 6-phosphate, important enzyme in the transport and metabolism of dietary sucrose. Streptococcus mutans coordinates the activities of enzyme IIscr and sucrose-6-phosphate hydrolase by transcriptional repressor ScrR binding to the promoter regions of the scr regulon |
| 3.2.1.B3 | sucrose + H2O |
sucrose uptake and catabolism play important roles in colonization of the murine nasopharynx and an accessory role in the infection of the lung, but is dispensable in a model of bacteraemia. The two sucrose uptake systems are differentially expressed such that one is dominant during lung infection while the other is dominant in colonization of the nasopharynx. Sucrose is a major carbon source utilized by Streptococcus pneumoniae during colonization and infection of mucosal surfaces |
