The Pst system of Streptococcus mutans is important for phosphate transport and adhesion to abiotic surfaces [0.03%]
乳链菌突变种的Pst系统对于磷酸盐运输和非生物表面黏附是重要的
D E Luz,R S L Nepomuceno,B Spira et al.
D E Luz et al.
The Pst system is a high-affinity inorganic phosphate transporter found in many bacterial species. Streptococcus mutans, the etiological agent of tooth decay, carries a single copy of the pst operon composed of six cistrons (pstS, pstC1, ps...
