The present invention relates to a nucleic acid molecule, which encodes a polypeptide having alcohol dehydrogenase activity, in particular methanol dehydrogenase activity, comprising having a nucleotide sequence selected from the group consisting of: (i) a nucleotide sequence as set forth in any one of SEQ ID NOs: 1 (mdh2-MGA3), 3 (mdh3-MGA3), or 5 (mdh2-PB1); (ii) a nucleotide sequence having at least 90% sequence identity, more particularly at least 91, 92, 93, 94, 95, 96, 97, 98 or 99% sequence identity, with a nucleotide sequence as set forth in any one of SEQ ID NOs: 1, 3 or 5; (iii) a nucleotide sequence which is degenerate with any one of the nucleotide sequences of SEQ ID NOs: 1, 3 or 5; (iv) a nucleotide sequence which is a part of the nucleotide sequence of any one of SEQ ID NOs: 1, 3 or 5, or of a nucleotide sequence which is degenerate with a sequence of SEQ ID NOs: 1, 3 or 5; (v) a nucleotide sequence encoding all or part of a polypeptide whose amino acid sequence is set forth in any one of SEQ ID NOs: 2 (Mdh2-MGA3), 4 (Mdh3-MGA3) or 6 (Mdh2-PB1); and (vi) a nucleotide sequence encoding all or part of a polypeptide which has an amino acid sequence having at least 90% sequence identity, preferably at least 91, 92, 93, 94, 95, 96, 97, 98 or 99% sequence identity, with an amino acid sequence as set forth in any one of SEQ ID NOs: 2, 4 or 6; or a nucleic acid molecule comprising a nucleotide sequence which is complementary to the nucleotide sequence of any one of (i) to (vi). Also provided are recombinant constructs, vectors and host cells comprising such a nucleic acid molecule and polypeptides encoded thereby. Such molecules may advantageously be used in the genetic modification of host cells, for example to introduce or modify methanol dehydrogenase activity.

[object Object]

The present invention relates to a method of microbial production of L-lysine from methanol and other substrates, and particularly improving the production of L-lysine from such substrates. The invention concerns a method for producing L-lysine in, said method comprising overexpressing an aspartate kinase III (AKIII) enzyme in said. In particular the method may concern introducing a nucleic acid molecule comprising a nucleotide sequence encoding an AKIII enzyme into a. The invention also relates to amicro-organism which overexpresses an AKIII enzyme, nucleic acid molecules which encode polypeptides having AK activity, polypeptides which have AK activity and host cells and vector systems comprising the nucleic acid molecules or vector.

Method of L-lysine production

The present invention relates to compounds which are nystatin derivatives and are anti-fungal agents. 

Compound which is a nystatin derivative

The invention provides a nucleic acid molecule comprising: (a) a nucleotide sequence as shown in SEQ ID No. 35; or (b) a nucleotide sequence which is the complement of SEQ ID No. 35; or (c) a nucleotide sequence which is degenerate with SEQ ID No. 35; or (d) a nucleotide sequence hybridising under conditions of high stringency to SEQ ID No. 35, to the complement of SEQ ID No. 35, or to a hybridisation probe derived from SEQ ID No. 35 or the complement thereof; or (e) a nucleotide sequence having at least 80% sequence identity with SEQ ID No. 35; or (f) a nucleotide sequence having at least 65% sequence identity with SEQ ID No. 35 wherein said sequence preferably encodes or is complementary to a sequence encoding a nystatin PKS enzyme or a part thereof. Also provided are part of such molecules and polypeptides (and parts thereof) encoded by such a nucleic acid molecule, and the use of such molecules and polypeptides in facilitating nystatin biosynthesis and in the synthesis of nystatin derivatives and novel polyketide as macrolide structures.

Genes encoding a nystatin polyketide synthase and their manipulation and utility

The invention provides a nucleic acid molecule comprising: (a) a nucleotide sequence as shown in SEQ ID No. 35; or (b) a nucleotide sequence which is the complement of SEQ ID No. 35; or (c) a nucleotide sequence which is degenerate with SEQ ID No. 35; or (d) a nucleotide sequence hybridising under conditions of high stringency to SEQ ID No. 35, to the complement of SEQ ID No. 35, or to a hybridisation probe derived from SEQ ID No. 35 or the complement thereof; or (e) a nucleotide sequence having at least 80% sequence identity with SEQ ID No. 35; or (f) a nucleotide sequence having at least 65% sequence identity with SEQ ID No. 35 wherein said sequence preferably encodes or is complementary to a sequence encoding a nystatin PKS enzyme or a part thereof. Also provided are part of such molecules and polypeptides (and parts thereof) encoded by such a nucleic add molecule, and the use of such molecules and polypeptides in facilitating nystatin biosynthesis and in the synthesis of nystatin derivatives and novel polyketide as macrolide structures.
