Definition of lysK

• Curated proteins or TIGRFams with EC 3.5.1.132
• Predicted: UniProt sequence A9A1L3: RecName: Full=Putative [LysW]-lysine/[LysW]-ornithine hydrolase {ECO:0000256|HAMAP-Rule:MF_01120}; EC=3.5.1.130 {ECO:0000256|HAMAP-Rule:MF_01120}; EC=3.5.1.132 {ECO:0000256|HAMAP-Rule:MF_01120};
• Comment: TK0274 from Thermococcus kodakarensis (Q5JFW4) is bifunctional, for lysine and ornithine synthesis (PMC5076833). NMAR_RS06940 (A9A1L3) is probably bifunctional for [LysW]-ornithine and [LysW]-lysined hydrolase; this would explain how ornithine is formed in Nitrosopumilus maritimus, and it is similar to [LysW]-lysine hydrolyze Q8VUS5, which is reported to hydrolyze acetyllysine or acetylornithine in vitro.
