locus-tag	class	description
H3H30_gp26	COG1974	Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair
H3H30_gp48	COG3561	AntA/AntB antirepressor
H3H30_gp50	COG0582	viral genome integration into host DNA
H3H30_gp81	COG3772	lysozyme
