   4.1.1.101 | down |
expression of malolactic enzyme is decreased in the presence of ethanol |
733686 |
| 4.1.1.101 | more |
enzyme is constitutively expressed. Addition of L-malic acid (37 mM) to the growth medium results in increased activity, addition of the D-isomer alone or the racemic mixture results in lower activities. Addition of the main sugars in apple juice (fructose, sucrose, and glucose) to the growth medium in the presence of malic acid represses production of the enzyme. In the absence of malic acid, addition of sugars to the growth medium somewhat increases the residual malolactic activity |

| 4.1.1.101 | up |
expression of malolactic enzyme is inducible by the presence of malic acid, with increased expression in the middle of malolactic fermentation. Expression is also increased at low pH values |
733686 |
| 4.1.1.101 | up |
expression of mle genes encoding malolactic enzyme mleS, the putative L-malate transporter MleT, and the putative regulator MleR is induced by L-malic acid and it is not subject to carbon catabolite repression |

| 4.1.1.101 | up |
gene expression is up 250fold increased in the presence of L-malate |
-, 748018 |
| 4.1.1.101 | up |
optimal conditions for expressions are presence of 7 g/l L-malic acid in the growth medium |
