摘要:
The present invention relates to a method of producing keratin hydrolysate comprising the steps of: i) reacting keratin material with a protease; and ii) reacting keratin material with a chemical oxidant; wherein step ii occurs: a) after step i); b) during step i) when the selected protease hydrolyses under the pH conditions used for the chemical reaction and/or c) prior to step i) when the selected protease hydrolyses under the reaction conditions used for the chemical reaction; keratin hydrolysate so produced and uses thereof.

摘要:
In one aspect of the present invention there is provided a method for preparing a variant lipid acyltransferase enzyme comprising expressing in a host organism a nucleotide sequence which has at least 90% identity with a nucleotide sequence encoding a parent lipid acyltransferase and comprises at least one modification (suitably at least two modifications) at a position(s) which corresponds in the encoded amino acid sequence to an amino acid(s) located in a) the canyon region of the enzyme (i.e. preferably amino acid residues 31, 27, 85, 86, 119, and 120); and/or b) insertion site 1 (i.e. amino acid residues 22-36) and/or c) insertion site 2 (i.e. amino acid residues 74-88), wherein the canyon region, insertion site 1 and/or insertion site 2 are defined as that region which when aligned based on primary or tertiary structure corresponds to the canyon region, insertion site 1 or insertion site 2 (or the corresponding amino acid residues taught above) of the enzyme shown herein as SEQ ID No. 16 or 6. Preferable modifications are one or more of the following L3 IQ, H, N, T, F, Y or C (preferably L31 Q); M27R, G, H, K, Y, D, N, V, C, Q, L, E, S or F (preferably M27V); V85H, R5 D or E; I86R,Y, S, V, I, As T, M, F, C or L (preferably I86S or A); Al 19T or I; Y120K or E; W122S, L or A (preferably W122L); E201R; Q245S; F235A or V; W232G or S; and/or A236G or E.
