Abstract

Polinucleótido, caracterizado porque comprende una secuencia de nucleótidos que codifica un polipéptido que es por lo menos 95% idéntico a la SEQ ID NO: 2, que tiene a) un dominio kringle N-terminal único homólogo a un dominio kringle del plasminógeno humano nativo, en el que los cuatro últimos residuos de aminoácidos dentro del dominio kringle son V, P, Q y C; y b) un sitio de activación del dominio C-terminal y un dominio de serina proteasa homólogos a los dominios correspondientes en el plasminógeno humano; en los que el polipéptido se une a lisina inmovilizada.

Diseño del vector de expresión
5 La secuencia de aminoácidos para (TLA6003)-plasminógeno se muestra en SEQ ID NO: 2. En un polinucleótido que tiene la secuencia de nucleótidos que codifica (TAL6003)-plasminógeno se optimizaron los codones por la expresión de
E. coli y la estabilidad de ARNm para proporcionar la secuencia de ADN tal como se muestra en SEQ ID NO: 1. Este polinucleótido se clonó en los sitios Ndel y BamHI del vector de expresión de E. coli pET24b(+) (Novagen; Madison, WI) para producir la proteína citosólica.
10 Como se ilustra en la tabla 1, la expresión en bacterias (por ejemplo E. coli) proporciona un polipéptido (TAL6003)-plasminógeno recombinante que tiene la secuencia de aminoácidos tal como se muestra en SEQ ID NO: 2 (es decir, un (TAL6003)-plasminógeno recombinante con una metionina N-terminal (es decir, M1) que precede inmediatamente el residuo de aminoácidos de arginina (es decir, R2) correspondiente a la arginina en la posición 70 (es
15 decir, R70) de la secuencia de aminoácidos de plasminógeno humano nativo mostrado en SEQ ID NO: 4 (véase también, por ejemplo, la Figura 3). Dicho producto recombinante es susceptible a escisión adicional para producir proteínas adicionales que tienen extremos N-terminales diferentes que incluyen una proteína con una lisina N-terminal (es decir, K10) o valina (es decir, V11) correspondiente, respectivamente, a la lisina en la posición 78 (es decir, K78) o la valina en la posición 79 (es decir, V79) de plasminógeno humano nativo.

Tabla 1: Extremos N-terminales de plasmina(plasminógeno) nativo (por ejemplo, basado en SEQ ID NO:4) y (TAL6003)-plasmina(plasminógeno) (por ejemplo, basado en SEQ ID NO: 2, o su variante)
Plasminógeno nativo que comprende una secuencia lectora de 19 aminoácidos (por ejemplo basado en SEQ ID NO: 4):
“Lys-plasminógeno” nativo (es decir, escisión de secuencia lectora): (véase SEQ ID NO:5)
Especies de plasmina nativa posibles basadas en escisión, si es cualquiera, de Lys-Plasminógeno: (véase SEQ ID NO: 14) (véase SEQ ID NO: 13) (véase SEQ ID NO: 12)
Polipéptidos de (TAL6003)-plasminógeno recombinantes de la presente invención: (por ejemplo, basados en SEQ ID NO: 2)
Proteínas adicionales basadas en escisión adicional de un (TAL6003)-plasminógeno (por ejemplo, basadas en SEQ ID NO: 2) (véase SEQ ID NO: 11) K10V11YLSEC ….. (SEQ ID NO: 5) V11YLSEC …..
↓ indica sitios de escisión potencial
Expresión y purificación de (TAL6003)-plasminógeno
El vector de expresión que comprende el ADN que codifica (TAL6003)-plasminógeno se transforma en una variedad de
25 células que incluyen Bl21(DE3)RIL (Stratagene, La Jolla, CA), BL21(DE3) (genotipo: F -ompT hsdSB (rB-mB-) gal dcm (DE3)) (EMB Biosciences, Inc., San Diego, CA), y BLR(DE3) (genotipo: F-ampT hsdSB (rB -mB -) gal dcm (DE3) Δ(srl-recA)306::Tn10(TetR)), y la sobreexpresión de proteína seguida por la inducción por IPTG 1mM (isopropil-beta-D-tiogalactopiranósido) se analizó por SDS-PAGE. Los estimados de expresión fueron, como mínimo, de aproximadamente 250 mg/l de cultivo celular en matraces agitadores.
30 La célula tipo BL21(DE3)RIL se diseña para expresar ARNt de E. coli raros que codifican para Arg, IIe, y Leu. Además, tanto BL21(DE3) como BLR(DE3) son cepas B de E. coli que se clasifican como no patogénicas para humanos y animales basados en la ausencia de factores de virulencia y colonización. Las células BLR(DE3) carecen del gen recA para recombinación de ADN, y no se ha informado de la inducción de fago lambda con estas células. Un banco celular
