标题:Ab-initio, template-independent synthesis of nucleic acids using thermostable enzymes
发明人：RANDRIANJATOVO-GBALOU IRINA; SAID AHMED; RAHIER RENAUD
权利人:SYNHELIX
摘要:The invention relates to the field of nucleic acid synthesis or sequencing, more specifically to methods for ab-initio synthesis of nucleic acids, comprising contacting a nucleotide with a free 3′-hydroxyl group, with at least one nucleoside triphosphate, or a combination of nucleoside triphosphates, in the presence of an archaeal DNA primase or a functionally active fragment and/or variant thereof, thereby covalently binding said nucleoside triphosphate to the free 3′-hydroxyl group of the nucleotide. It also relates to isolated functionally active fragments of archaeal DNA primases which are capable of both ab-initio single-stranded nucleic acid synthesis activity and template-independent terminal nucleotidyl transferase activity.

摘要:The invention relates to methods for template-independent synthesis of nucleic acids, comprising iteratively contacting an initiator sequence comprising a 3′-end nucleotide with a free 3′-hydroxyl group, with at least one nucleoside triphosphate, or a combination of nucleoside triphosphates, in the presence of an archaeal DNA primase or a functionally active fragment and/or variant thereof, thereby covalently binding said nucleoside triphosphate to the free 3-hydroxyl group of the 3-end nucleotide. It also relates to isolated functionally active fragments of archaeal DNA primases which are capable of template-independent terminal nucleotidyl transferase activity but are devoid of a template-independent primase activity.

标 题 :Synthesis of hydroxyl-terminated polybutadienes using glycol ether solvents
发明人：KNIFTON JOHN F; MARQUIS EDWARD T
权利人:TEXACO CHEMICAL
摘要:Disclosed is an improvement in a process for polymerizing 1,3-butadiene selectively to form relatively low molecular weight hydroxyl-terminated polybutadiene oligomers in the presence of an aqueous solution of hydrogen peroxide which comprises the use of a glycol ether solvent to produce butadiene oligomers having a high degree of OH functionality and suppression of formation of solid or gel-type insoluble rubber by-products.

标题 :Synthesis of low molecular weight glycol ethers from oxiranes plus olefins
发明人：KNIFTON JOHN F
权利人:TEXACO CHEMICAL
摘要:Disclosed is a process for preparation of monoalkyl ethers by reacting low molecular weight olefins and the corresponding oxiranes, in the presence of a catalyst comprising an acidic heterogeneous or homogeneous catalyst, generally represented by the equation: ##STR1## where R, R', R' may be hydrogen or an alkyl radical.
