locus-tag	class	description
VPT02_035	COG0462	Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib-5-P)
VPT02_042	COG0639	Hydrolyzes diadenosine 5',5'''-P1,P4-tetraphosphate to yield ADP
VPT02_080	COG3201	nicotinamide mononucleotide transporter
VPT02_102	COG0328	RNA-DNA hybrid ribonuclease activity
VPT02_106	COG0602	queuosine metabolic process
VPT02_107	COG0209	Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides
VPT02_107	COG1327	Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes
VPT02_110	COG1328	CTP reductase activity
VPT02_124	COG0272	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

VPT02_138	COG0258	In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity
VPT02_138	COG0749	In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity
VPT02_139	COG0756	dUTP diphosphatase activity
