Patent number: 8975041Abstract: The present invention relates to novel Prolipase-Bovine trypsinogen (PLBTR) fusion proteins, the genes encoding them, and the production and uses thereof. More specifically, the present invention relates to methods of producing in optimal quantities PLBTR fusion proteins which comprise a heterologous polypeptide which is normally susceptible to autocatalytic activity. More particularly, the present invention relates to fusion proteins which comprise an heterologous polypeptide, such as a serine protease, fused to a lipase signal sequence, which can be expressed by recombinant host cells in desired amounts. The present invention further relates to polynucleotides encoding such fusion proteins, to expression vectors for expression of such fusion proteins, to host cells transformed with such polynucleotides/vectors, and to methods of generating such fusion proteins.Type: GrantFiled: October 26, 2009Date of Patent: March 10, 2015Assignee: Biocon LimitedInventors: Nagaraj Govindappa, Nandini Nataraj, Sanjay Tiwari, Partha Hazra, Mukesh Babuappa Patale, Gokul Jothiraman, Kedarnath Sastry

Patent number: 8802816Abstract: The invention relates to methods of separation and/or purification of impurities yielding a purified heterologous protein product devoid of related impurities or with substantially minimal quantities of such glycosylated impurities. More specifically, the invention relates to the identification of glycosylated forms of insulin analogues such as glargine impurities characterized post expression in yeast based systems such as Pichia pastoris. The invention also relates to methods used to clone gene encoding the protein insulin glargine; inserting the related gene in a suitable yeast host; producing culture of the recombinant strain, stimulating expression of the heterologous polypeptide, its secretion and purification post fermentation and related enzymatic conversions.Type: GrantFiled: April 3, 2008Date of Patent: August 12, 2014Assignee: Biocon LimitedInventors: Partha Hazra, Nitesh Dave, Vivekanandan Kannan, Sanjay Tiwari, Anuj Goel, Harish Iyer, Nita Roy, Krishnamurthy Venkatesan, Anoop Vasudevan, Anupama Jagadish, Goldy Sachdev, Mukesh Babuappa Patale

Patent number: 8778659Abstract: The disclosure relates to method of reducing O-glycosylation levels of the insulin or insulin analog precursor molecule produced by Pichia sp. The present disclosure provides genetically engineered knock-out strains of methylotrophic yeast including Pichia and especially Pichia pastoris by disruption of Protein mannosyl transferase (PMT) genes and rendering them capable of producing heterologous proteins with reduced glycosylation. Vectors, which comprise coding sequences for PMT1, PMT2, PMT4, PMT5, and PMT6 genes, for transforming methylotrophic yeasts are contemplated by the present disclosure. PMT inactivated strains of this disclosure have been deposited at MTCC, Chandigarh. The strains are PMT1/GS115 (MTCC 5515), PMT4/GS115 (MTCC 5516), PMT5/GS115 (MTCC 5517) and PMT6/GS115 (MTCC 5518).Type: GrantFiled: March 29, 2010Date of Patent: July 15, 2014Assignee: Biocon LimitedInventors: Nagaraj Govindappa, Komal Kanojia, Krishnamurthy Venkatesan, Nitesh Dave, Mukesh Babuappa Patale, Sanjay Tiwari, Kedarnath N. Sastry, Harish Iyer
