摘要:
A gene associated with sensitivity to the antimycotic agent, aureobasidin A, has been isolated. The gene can be detected in a variety of cell types, and variant forms of the gene have been identified in mutant yeast strains. The proteins encoded by these genes are useful in diagnosing and treating mycoses.

摘要:
An isolated hyperthermostable .beta.-galactosidase gene derived from Pyrococcus furiosus is described. Examples include DNA sequences shown in SEQ ID NO. 2 and SEQ ID NO. 4 and DNAs hybridizable with these DNAs. A method of cloning the hyperthermostable .beta.-galactosidase gene in which each of the above sequences or portions thereof is used as a probe or primer is described. A process for producing a hyperthermostable .beta.-galactosidase by culturing a transformant into which a plasmid containing each of the above genes has been introduced is described. A particularly preferred gene encodes an SDS-resistant hyperthermostable .beta.-galactosidase.

摘要:
This invention relates to Aureobasidins useful as an antifungal agent having broader spectrum. The compound according to this invention includes a cyclic depsipeptide consisting of one hydroxy acid residue having A.sup.1, 3 amino acid residues having C.sup.1, F.sup.1 and H.sup.1, respectively, 4 N-methylamino acid residues having B.sup.1, D.sup.1, G.sup.1 and I.sup.1, respectively, and 1 cyclic amino acid residue having E.sup.1. The typical compound includes one wherein A.sup.1 is CH.sub.3 CH.sub.2 CH(CH.sub.3)--, B.sup.1 is (CH.sub.3).sub.2 CH--, C.sup.1 is benzyl, cyclohexylmethyl, p-fluorobenzyl, benzyloxymethyl, benzyloxybenzyl, methoxybenzyl, cyclohexylmethyloxybenzyl or the like, D.sup.1 is methyl, benzyl, hydroxymethyl or the like, E.sup.1 is --(CH.sub.2).sub.3 --, F.sup.1 is CH.sub.3 CH.sub.2 CH(CH.sub.3)--, G.sup.1 is (CH.sub.3).sub.2 CH--, H.sup.1 is (CH.sub.3).sub.2 CHCH.sub.2 -- and I.sup.1 is (CH.sub.3).sub.2 C(OH)--. The compound according to this invention has an excellent activity against not only Candida but also Cryptococcus and Aspergillus.

摘要:
This invention provides an antibody having antigen binding activity and which has a heavy chain constant region into which has been introduced an RGDS amino acid sequence giving the antibody affinity for cells, including macrophages. The antibody exhibits artificial cell adhesive activity which is the newly expressed activity that results from insertion of the RGDS amino acid sequence. This antibody having artificial cell adhesive activity can accelerate the phagocytosis of macrophages, and can activate other effector cells. Therefore, this antibody contributes to the self-defense mechanism.
摘要:
Polypeptides are provided which have a calpain inhibitory activity. The polypeptides have an activity like that of natural human calpastatin but are significantly shorter in length than natural human calpastatin. The polypeptides are suited for synthetic manufacture.
