Eksempler på enzyme

• Homozygous mutants with only 2 % residual enzyme activity were recovered in progeny of inter se matings of heterozygotes.

• It seems that these enzymes played integral roles in the protection of plants from oxidative stress.

• Most zygote isolations were completed using cellulase and pectinase because the enzymes substantially improved this process.

• The reasons for the dominance of kinase (and other enzyme) inhibitors as targets for modern cancer therapeutics are centred on the enzyme substrate-binding site.

• Figure 1 highlights these organellar compartments and provides a general description of their resident metabolic pathways and enzymes.

• This view was supported by biochemical evidence of the presence of lysosomal enzymes.

• However, it was difficult to reconcile such a model with many properties of the enzymes.

• A role for these enzymes in the hostparasite interaction, or in the increased susceptibility to secondary infections has yet to be demonstrated.

• Changes in gene expression include those concerned with hormone receptors, signalling and glycolytic enzymes.

• The percentage of genetic variation between regions, among populations within regions and within populations was determined for each enzyme.

• The proportion of genetic variation between regions, among populations within regions, and within populations was calculated for each enzyme (table 2).

• This suggests that enzyme(s) with peroxidase activity are released following fertilisation.

• This is unfortunate since the oocyst is basically a dormant stage, and the activities of many enzymes of interest would be expected to be low.

• To date, studies on seeds have failed to provide an enzyme as a transitional developmental marker between the dormant and germinating states.

• In so doing, these enzymes may have generated selective pressure to be retained and, therefore, broken free of the invasion-elimination cycle of most homing sequences.
