Techniques Used: Sequencing

Affinity of recombinant PBP3 proteins for fluorescent-labeled Bocillin. One hundred-seventy nanograms of each PBP3 was incubated for 30 min at 37°C with 2 to 12 μM Bocillin. Error bars indicate ±1 standard deviation. PBP3 proteins tested were expressed from ftsI of H. influenzae Rd (control); BLNAR strains 1312 (group I), 1311, and 1369 (group II); and single-substitution alleles of group I (Arg517 to His) and group II (Asn526 to Lys) PBP3.
