CLAIMS 1. A lipid acyltransferase wherein the lipid acyltransferase comprises the amino acid sequence shown as SEQ ID No. 90, or an amino acid sequence which has 95% or more identity with SEQ ID No. 90. 2. A lipid acyltransferase according to claim 1 wherein the lipid acyltransferase is characterised as an enzyme which possesses acyl transferase activity and which comprises the amino acid sequence motif GDSX, wherein X is one or more of the following amino acid residues L, A, V, I, F, Y, H, Q, T, N, M or S. 3. A lipid acyltransferase according to claim 1 or claim 2 wherein the lipid acyltransferase is obtainable (or obtained) from the genera Aeromonas. 4. A lipid acyltransferase according to any one of claims 1-3 wherein the lipid acyltransferase has one or more of the following characteristics: (a) when tested using the "Transferase Assay in a Low Water Environment", measured after a time period selected from 30, 20 or 120 minutes, has a relative transferase activity of at least 1%; (b) when tested using the "Transferase Assay in High Water Egg Yolk" in an egg yolk with 54% water, has up to 100% relative transferase activity; or (c) when tested using the "Transferase Assay in Buffered Substrate" has at least 2% acyltransferase activity. 5. A lipid acyltransferase according to claim 4 wherein the lipid acyltransferase has more than two of the following characteristics (a) when tested using the "Transferase Assay in a Low Water Environment", measured after a time period selected from 30, 20 or 120 minutes, has a relative transferase activity of at least 1%; (b) when tested using the "Transferase Assay in High Water Egg Yolk" in an egg yolk with 54% water, has up to 100% relative transferase activity; or (c) when tested using the "Transferase Assay in Buffered Substrate" has at least 2% acyltransferase activity. 6. A lipid acyltransferase according to claim 4 wherein the lipid acyltransferase has more than three of the following characteristics (a) when tested using the "Transferase Assay in a Low Water Environment", measured after a time period selected from 30, 20 or 120 minutes, has a relative transferase activity of at least 1 %; (b) when tested using the "Transferase Assay in High Water Egg Yolk" in an egg yolk with 54% water, has up to 100% relative transferase activity; or (c) when tested using the "Transferase Assay in Buffered Substrate" has at least 2% acyltransferase activity. 7. A lipid acyltranferase according to claim 4 wherein the lipid acyltransferase has all of the following characteristics (a) when tested using the "Transferase Assay in a Low Water Environment", measured after a time period selected from 30, 20 or 120 minutes, has a relative transferase activity of at least 1%; (b) when tested using the "Transferase Assay in High Water Egg Yolk" in an egg yolk with 54% water, has up to 100% relative transferase activity; or (c) when tested using the "Transferase Assay in Buffered Substrate" has at least 2% acyltransferase activity. 8. A lipid acyltransferase according to any one of the preceding claims wherein the lipid acyltransferase comprises an amino acid sequence which has 98% or more identity with SEQ ID No. 90. 9. A lipid acyltransferase according to any one of the preceding claims wherein the lipid acyltransferase comprises the amino acid sequence shown as SEQ ID No. 90. 10. A lipid acyltransferase according to any one of the preceding claims wherein the lipid acyltransferase has the amino acid sequence shown as SEQ ID No. 90. 11. A lipid acyltransferase enzyme according to any one of the preceding claims wherein the lipid acyltransferase is immobilised. 12. A food or feed enzyme composition which contains said lipid acyltransferase according to any one of the preceding claims.
