| dynamic aspects of the structured cell population in a swarming colony of proteus mirabilis. | proteus mirabilis forms a concentric-ring colony by undergoing periodic swarming. a colony in the process of such synchronized expansion was examined for its internal population structure. in alternating phases, i.e., swarming (active migration) and consolidation (growth without colony perimeter expansion), phase-specific distribution of cells differing in length, in situ mobility, and migration ability on an agar medium were recognized. in the consolidation phase, the distribution of mobile cel ... | 2000 | 10629184 |
| role and mechanism of action of c. pvuii, a regulatory protein conserved among restriction-modification systems. | the pvuii restriction-modification system is a type ii system, which means that its restriction endonuclease and modification methyltransferase are independently active proteins. the pvuii system is carried on a plasmid, and its movement into a new host cell is expected to be followed initially by expression of the methyltransferase gene alone so that the new host's dna is protected before endonuclease activity appears. previous studies have identified a regulatory gene (pvuiic) between the dive ... | 2000 | 10629196 |
