Eleven strains of Alcaligenes denitrificans subsp. xylosoxydans produced a beta-lactamase with a pI of 5.7 with kinetic data characteristic of a PSE-1-type enzyme. A CARB-type enzyme was identified by using an intragenic DNA probe of blaCARB. Hybridization of genomic DNA after XbaI restriction and pulsed-field electrophoresis suggested a chromosomal location for the gene.
11株反硝化产碱杆菌木糖氧化亚种产生了一种pI为5.7的β-内酰胺酶,其动力学数据具有PSE-1型酶的特征。通过使用blaCARB的基因内DNA探针鉴定出一种CARB型酶。XbaI酶切和脉冲场电泳后的基因组DNA杂交表明该基因位于染色体上。
