Claim 1
Independent Claim 4 words
t-PA having selected glycosylation.
Claim 2
Dependent Claim 4 words
t-PA having selected glycosylation.
Claim 3
Dependent Claim 5 words
t-PA when expressed by yeast.
Claim 4
Dependent Claim 5 words
t-PA when expressed by yeast.
Claim 5
Dependent Claim 12 words
A t-PA according to Claim 2 wherein the yeast is Saccharomyces cerevisiae.
Claim 6
Dependent Claim 113 words
A circular recombinant DNA compound of formula XXX wherein the repeated alphabetic sequences (the number of repetitions of which is arbitrarily depicted in said formula) therein represent the following: the "P" region comprises nucleotides whose sequence contains a yeast promoter and "pre-pro" signals consisting essentially of the "pre-pro" signals from the MFa1 gene; the "T" region comprises nucleotides whose sequence contains DNA for the synthesis of t-PA; the "H" region comprises the nucleotide whose sequence contains the 3'-end of the ADHI gene; the "A" region comprises the nucleotides whose ordered codons contain the URA3 gene; the "R" region comprises nucleotides whose sequence contains a REPIII and replication origin from the 2p yeast plasmid.
Claim 7
Dependent Claim 113 words
A circular recombinant DNA compound of formula XXX wherein the repeated alphabetic sequences (the number of repetitions of which is arbitrarily depicted in said formula) therein represent the following: the "P" region comprises nucleotides whose sequence contains a yeast promoter and "pre-pro" signals consisting essentially of the "pre-pro" signals from the MFa1 gene; the "T" region comprises nucleotides whose sequence contains DNA for the synthesis of t-PA; the "H" region comprises the nucleotide whose sequence contains the 3'-end of the ADHI gene; the "A" region comprises the nucleotides whose ordered codons contain the URA3 gene; the "R" region comprises nucleotides whose sequence contains a REPIII and replication origin from the 2p yeast plasmid.
Claim 8
Dependent Claim 24 words
A compound of Claim 4 wherein the "T" region does not contain the 3'-end untranslated region of the DNA for the synthesis of t-PA.

Claim 10
Dependent Claim 18 words
A cell or cell line according to Claim 8 wherein the DNA compound of Claim 4 expresses t-PA.
Claim 11
Dependent Claim 15 words
A method of producting t-PA which comprises culturing the cell line according to Claim 7.
