Methionine supplementation restored the growth of putative aminotransferase gene deletion mutant and increased the growth of the wild-type strain. Bacterial growth kinetics (OD600) of S. pneumoniae Taian-S3 wild-type strain (red, WT) and putative aminotransferase gene deletion mutant (black, ΔPA), with (empty square) or without (filled square) 0.5 mM methionine supplementation, were assessed every 30 min in THY medium (A) and every 60 min in CDM medium (B). Data are shown as mean ± standard deviation (SD) from three to five independent experiments. CDM chemically defined medium
