[Term] id: PR:Q07736 name: type I restriction enzyme EcoAI endonuclease subunit (Escherichia coli 15) def: "A DNA restriction-modification endonuclease that is a translation product of the hsdR gene in Escherichia coli 15." [PRO:DAN, PMID:6325176] comment: Category=organism-gene. Requested by=CRAFT. Note: Strain assignment was traced as follows. Early description of the enzyme was given in PMID:6325176, which indicated the strain as 15T-. According to PMID:16561414, 15T- is a thymine-less mutant of strain 15, also known as ATCC 9723 (https://www.atcc.org/products/all/9723.aspx). synonym: "hsdR (ECOLX-15)" EXACT PRO-short-label [PRO:DAN] synonym: "EcoAI (Escherichia coli)" EXACT [UniProtKB:Q07736] synonym: "R protein (Escherichia coli 15)" EXACT [PRO:DAN, UniProtKB:Q07736] synonym: "R.EcoAI (Escherichia coli 15)" EXACT [PRO:DAN, UniProtKB:Q07736] synonym: "type I restriction enzyme EcoAI R protein (Escherichia coli)" EXACT [UniProtKB:Q07736] synonym: "hsdR" RELATED Gene-based [UniProtKB:Q07736] synonym: "hsr" RELATED Gene-based [UniProtKB:Q07736] xref: UniProtKB:Q07736 is_a: PR:000050197 !
