RESUMO
Fluorescent probes are potential fluorophores that display signals based on the changes in tissue microenvironment, interactions with analytes or specific biochemical reactions. Metabolic enzymes are the most important protein involved in bacteria activities. Complex dynamics of biological processes in bacteria are elucidated by these metabolic enzymes-based fluorescent probes with high spatial resolution and sensitivity. Here, we review recent advances in metabolic enzyme-responsive fluorescent probes for bacteria imaging. It was organized according to enzyme classification systems, focused on fluorescence masking strategies, molecular mechanisms of enzyme activation, and bio-related applications.
RESUMO
A few bioinformatics tools have been used to find out conserved regions as probes. We have developed a system based on a heuristic method with web interfaces to find out conserved regions against microbial genomes. The system runs in real time by using relative entropy in limited narrow regions and detecting similar regions between pair regions with local alignment. The system could be useful to find out conserved regions as genome-wide scale.
