Catalysis of the condensation of isopentenyl diphosphate and farnesyl diphosphate in the cis-configuration to form dehydrodolichyl diphosphate.

Catalysis of the reaction: L-phenylalanine = NH(4)(+) + trans-cinnamate.

Catalysis of the reactions: a 9-cis-epoxycarotenoid + O2 = 2-cis,4-trans-xanthoxin + a 12'-apo-carotenal; 9-cis-violaxanthin + O2 = 2-cis,4-trans-xanthoxin + (3S,5R,6S)-5,6-epoxy-3-hydroxy-5,6-dihydro-12'-apo-beta-caroten-12'-al; and 9'-cis-neoxanthin + O2 = 2-cis,4-trans-xanthoxin + (3S,5R,6R)-5,6-dihydroxy-6,7-didehydro-5,6-dihydro-12'-apo-beta-caroten-12'-al.

A developmental process, independent of morphogenetic (shape) change, that is required for the hindbrain to attain its fully functional state. The hindbrain is the region consisting of the medulla, pons and cerebellum. Areas of the hindbrain control motor and autonomic functions.

The process in which the anatomical structure of the medulla oblongata is generated and organized. The medulla oblongata lies directly above the spinal cord and controls vital autonomic functions such as digestion, breathing and the control of heart rate.

The process whose specific outcome is the progression of rhombomere 6 over time, from its formation to the mature structure. Rhombomeres are transverse segments of the developing rhombencephalon. Rhombomeres are lineage restricted, express different genes from one another, and adopt different developmental fates. Rhombomeres are numbered in anterior to posterior order.

Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of cholesterol.

Any process that modulates the rate, frequency, or extent of cholesterol metabolism, the chemical reactions and pathways involving cholesterol, cholest-5-en-3 beta-ol, the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones.

Any process that modulates the frequency, rate or extent of a sterol biosynthetic process.

The process whose specific outcome is the progression of rhombomere 7 over time, from its formation to the mature structure. Rhombomeres are transverse segments of the developing rhombencephalon. Rhombomeres are lineage restricted, express different genes from one another, and adopt different developmental fates. Rhombomeres are numbered in anterior to posterior order.

Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of cholesterol.

Any process that decreases the rate, frequency, or extent of cholesterol metabolism, the chemical reactions and pathways involving cholesterol, cholest-5-en-3 beta-ol, the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones.

The process whose specific outcome is the progression of rhombomere 4 over time, from its formation to the mature structure. Rhombomeres are transverse segments of the developing rhombencephalon. Rhombomeres are lineage restricted, express different genes from one another, and adopt different developmental fates. Rhombomeres are numbered in anterior to posterior order.

Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of cholesterol.

Any process that increases the rate, frequency, or extent of cholesterol metabolism, the chemical reactions and pathways involving cholesterol, cholest-5-en-3 beta-ol, the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones.

Any process that activates or increases the frequency, rate or extent of a sterol biosynthetic process.

The process whose specific outcome is the progression of rhombomere 5 over time, from its formation to the mature structure. Rhombomeres are transverse segments of the developing rhombencephalon. Rhombomeres are lineage restricted, express different genes from one another, and adopt different developmental fates. Rhombomeres are numbered in anterior to posterior order.

Catalysis of the reaction: a gibberellin + 2-oxoglutarate + O2 = a 2-beta-hydroxygibberellin + succinate + CO2.

The process that gives rise to the hindbrain. This process pertains to the initial formation of a structure from unspecified parts. The hindbrain is the region consisting of the medulla, pons and cerebellum. Areas of the hindbrain control motor and autonomic functions.

The process that contributes to the act of creating the structural organization of the hindbrain. This process pertains to the physical shaping of a rudimentary structure. The hindbrain is the region consisting of the medulla, pons and cerebellum. Areas of the hindbrain control motor and autonomic functions.
