Intercity spread of echovirus 6 in Shandong Province, China: application of environmental surveillance in tracing circulating enteroviruses.

abstract：:Streptomyces exfoliatus SMF19 produced two types of extracellular beta-lactamase-inhibiting proteins, 48 (beta LIP-I) and 33 (beta LIP-II) kDa. The inhibition mode of beta LIP-I on Bacto Penase and benzylpenicillin as substrates was uncompetitive (i.e., both Km and Vmax were changed), while that of beta LIP-II was non...
