Low molecular weight protein tyrosine phosphatase
Low molecular weight protein tyrosine phosphatases (LMW-PTP) are a family of small soluble single-domain enzymes that are characterized by a highly conserved active site motif (V/I)CXGNXCRS and share no sequence similarity with other types of protein tyrosine phosphatases (PTPs). LMW-PTPs play important roles in many biological processes and are widely distributed in prokaryotes and eukaryotes.
