Ade5_like 5-aminoimidazole-4-(N-succinylcarboxamide) ribonucleotide (SAICAR) synthase; Eukaryotic group of SAICAR synthetases represented by the Drosophila melanogaster, N-terminal, SAICAR synthetase domain of bifunctional Ade5. The Ade5 gene product (CAIR-SAICARs) catalyzes the sixth and seventh steps of the de novo biosynthesis of purine nucleotides (also reported as seventh and eighth steps). SAICAR synthetase converts 5-aminoimidazole-4-carboxyribonucleotide (CAIR), ATP, and L-aspartate into 5-aminoimidazole-4-(N-succinylcarboxamide) ribonucleotide (SAICAR), ADP, and phosphate.

GT1, myb-like, SANT family; GT-1, a myb-like protein, is one of the GT trihelix transcription factors. GT-1 binds the GT cis-element of rbcS-3A, a light-induced gene, as a dimer. Arabidopsis GT-1 is a trans-activator and acts in the stabilization of components of the transcription pre-initiation complex comprised of TFIIA-TBP-TATA. The isolated GT-1 DNA-binding domain is sufficient to bind DNA. This region closely resembles the myb domain, but with longer helices. It has been proposed that GT-1 may respond to light signals via calcium-dependent phosphorylation to create a light-modulated molecular switch. These proteins are members of the SANT/myb group. SANT is named after 'SWI3, ADA2, N-CoR and TFIIIB', several factors that share this domain. The SANT domain resembles the 3 alpha-helix bundle of the DNA-binding Myb domains and is found in a diverse set of proteins.

The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits
(labeled illustration).
Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
