| - | Streptococcus pyogenes, or Group A Streptococcus (GAS), is a pathogenic bacterium that causes a variety of infectious diseases. The GAS genome encodes one protein tyrosine phosphatase, SP-PTP, which plays an essential role in the replication and virulence maintenance of GAS. Herein, we present the crystal structure of SP-PTP at 1.9 A resolution. Although SP-PTP has been reported to have dual phosphatase specificity for both phosphorylated tyrosine and serine/threonine, three-dimensional structural analysis showed that SP-PTP shares high similarity with typical low molecular weight protein tyrosine phosphatases (LMWPTPs), which are specific for phosphotyrosine, but not with dual-specificity phosphatases, in overall folding and active site composition. In the dephosphorylation activity test, SP-PTP consistently acted on phosphotyrosine substrates, but not or only minimally on phosphoserine/phosphothreonine substrates. Collectively, our structural and biochemical analyses verified SP-PTP as a canonical tyrosine-specific LMWPTP.
