locus-tag	class	description
PS1_0004	ENOG4105C77	DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double-stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA (By similarity)
PS1_0007	ENOG4108UMW	Endonuclease that specifically degrades the RNA of RNA- DNA hybrids (By similarity)
PS1_0050	ENOG4105C0V	Provides the sole de novo source of dTMP for DNA biosynthesis (By similarity)
PS1_0050	ENOG4105C0V	Provides the sole de novo source of dTMP for DNA biosynthesis (By similarity)
PS1_0056	ENOG4108YYV	Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis (By similarity)
PS1_0060	ENOG4107104	thymidine kinase
PS1_0121	ENOG41090BQ	Glutaredoxin
