This activity is probably indispensable for denying or allowing access of transcriptional factors to their cognate DNA binding sites.
Our headlamps are indispensable tools, allowing us to see in this dark humid place.
In essence, we use the same mutants to identify and confirm the primary "hot spot" of interaction, as well as proximal sites that may be not indispensable for binding yet allow the formation of a stable covalent adduct.
Both nets and hooks are indispensable tools to allow efficient 'fishing' for multiple intermediates and products directly from the sophisticated process of SL metabolism.
Angiogenesis is an indispensable vehicle for tumor metastasis, allowing oxygen and nutrients to be replenished and cancer cells to be mobilized (Carmeliet and Jain, 2011).
Multispecies amino acid sequence comparison of the cytoplasmic regions of CEACAMs, therefore, allowed identification of sequence motifs which are indispensable for signalling of CEACAM receptors.
Moreover, synthesis of ferric reductase Cfl1 was upregulated, possibly to allow for capture of iron (III) ions, which are indispensable for Cat1 activity (Hammacott et al. 2000).
It allows "those measures not forbidden by international law which are indispensable for securing the complete submission of the enemy," according to the Lieber Code.
The primary sensory areas though, which are highly conserved, allow basic perception and stereotyped response to stimuli [ 87]- functions indispensable for any animal.
