DNA: genomic DESCRIPTION OF INSERT COMPONENT: Genome: Streptococcus equisimilis Gene symbol: skc Gene name: streptokinase Contains complete coding sequence?: U Strain: H46A Type of DNA: genomic Insert end: HindIII Insert end: HindIII Insert size (kb): 7.4 Cross references: Insert lengths(kb): 7.400000095367432 Gene product: streptokinase [skc] Target Gene: streptokinase |
| Comments |
Insert contains internal sites for HindIII (3), PstI (3), SalI (2), BamHI (2), AvaI (2) and EcoRI (1). Digestion of the plasmid with PstI yields fragments of 6.0, 2.5, 2.2, 1.1 kb. Restriction digests of the clone give the following sizes (kb): PstI--5.8, 2.3, 1.9, 1.2; BamHI--8.2, 3.1; EcoRI--6.2, 5.4; BamHI/EcoRI--4.0, 3.5, 2.8, 0.5; PvuII/AvaI--4.5, 2.8, 2.2, 1.7; HindIII--4.5, 2.6 doublet, 1.9. Mucoid colony morphology on agar supplemented with ampicillin (0.5 mg/ml). The entire streptokinase (skc) structural gene is on the 2.5 kb PstI fragment. Clone expresses streptokinase of Streptococcus equisimilis which is exported into the medium. |
