[Term] id: PR:P19704 name: type-1 restriction enzyme EcoAI specificity subunit (Escherichia coli 15) def: "A DNA restriction-modification specificity subunit that is a translation product of the hsdS gene in Escherichia coli 15." [PRO:DAN] 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: "hsdS (ECOLX-15)" EXACT PRO-short-label [PRO:DAN] synonym: "S protein (Escherichia coli 15)" EXACT [PRO:DAN, UniProtKB:P19704] synonym: "S.EcoAI (Escherichia coli 15)" EXACT [PRO:DAN, UniProtKB:P19704] synonym: "type I restriction enzyme EcoAI specificity protein (Escherichia coli 15)" EXACT [PRO:DAN, UniProtKB:P19704] synonym: "type I specificity subunit S.EcoAI (Escherichia coli)" EXACT [UniProtKB:P19704] synonym: "type-1 restriction enzyme EcoAI specificity subunit (Escherichia coli)" EXACT [UniProtKB:P19704] synonym: "hsdS" RELATED Gene-based [UniProtKB:P19704] synonym: "hss" RELATED Gene-based [UniProtKB:P19704] xref: UniProtKB:P19704 is_a: PR:000050199 !
