MICROBIOLOGY Correction for “Pyruvate cycle increases aminoglycoside efficacy and provides respiratory energy in bacteria,” by Yu-bin Su, Bo Peng, Hui Li, Zhi-xue Cheng, Tian-tuo Zhang, Jia-xin Zhu, Dan Li, Min-yi Li, Jin-zhou Ye, Chao-chao Du, Song Zhang, Xian-liang Zhao, Man-jun Yang, and Xuan-xian Peng, which was first published January 30, 2018; 10.1073/pnas.1714645115 (Proc Natl Acad Sci USA 115:E1578–E1587).
The authors note that, in footnote 2 on page E1578, the email “peng26@sysu.edu.cn” should instead appear as “pengb26@sysu.edu.cn.”
The authors also note that, on page E1580, right column, first full paragraph, line 6, “H2O” should instead appear as “2 H2O” and “3 CO2” should instead appear as “4 CO2.”
The authors note that Fig. 2 appeared incorrectly. The corrected figure and its legend appear below.

The P cycle and the TCA cycle in E. tarda. (A) Overview of the P cycle. Black line, overlapped pathway between the P cycle and the TCA; blue, a step of the TCA cycle, which does not exist in the P cycle; and red, pathways of the P cycle, which do not exist in the TCA cycle. ACO, aconitase; CS, citrate synthase; FUM, fumarase; GPT, glutamic-pyruvic transaminase; ICDH, isocitric dehydrogenase; MAE, malic enzyme (NAD-dependent malic enzyme and NADP-dependent malic enzyme); MDH, malate dehydrogenase; OGDH, α-oxoglutarate dehydrogenase; OXD, oxaloacetate decarboxylase; PDH, pyruvate dehydrogenase; PEPC, phosphoenolpyruvate carboxylase; PEPCK, phosphoenolpyruvate carboxykinase; PFO, pyruvate-flavodoxin oxidoreductase; PK, pyruvate kinase; SCS, succinyl-CoA synthetase; and SDH, succinic dehydrogenase. (B) Optical density (OD) (Left) and percent survival (Right) of EIB202. Cells were grown in LB medium and then incubated in M9 medium with acetate (10 mM) or oxaloacetate (10 mM). Result (B) is displayed as mean ± SEM; at least three biological repeats were carried out. Statistically significant values are indicated with asterisk (*P < 0.05, **P < 0.01) and determined by Student’s t test.
