phytochromobilin biosynthetic process

The chemical reactions and pathways resulting in the formation of phytochromobilin, which involves the oxidative cleavage of heme by a heme oxygenase(HO) to form biliverdin IX alpha.

trimethylamine monooxygenase activity

Catalysis of the reaction: N,N,N-trimethylamine + NADPH + H+ + O2 = N,N,N-trimethylamine N-oxide + NADP+ + H2O.

dimethylaniline-N-oxide aldolase activity

Catalysis of the reaction: N,N-dimethylaniline N-oxide = N-methylaniline + formaldehyde.

N,N-dimethylaniline monooxygenase activity

Catalysis of the reaction: N,N-dimethylaniline + NADPH + H+ + O2 = N,N-dimethylaniline N-oxide + NADP+ + H2O.

obsolete ubiquitin-calmodulin ligase activity

OBSOLETE. Catalysis of the reaction: n ATP + calmodulin + n ubiquitin = n AMP + n diphosphate + ubiquitin(n)-calmodulin.

phycocyanobilin biosynthetic process

The chemical reactions or pathway resulting in the formation of phycocyanobilin, which involves the oxidative cleavage of heme by a heme oxygenase (HO) to form biliverdin IX alpha. Biliverdin IX alpha is subsequently converted to phycocyanobilin by a ferredoxin-dependent oxidoreductase (PCYA).

alpha-glucan, water dikinase activity

Catalysis of the reaction: [(1->4)-alpha-D-glucosyl](n) + n ATP + n H2O = [(1->4)-6-phospho-alpha-D-glucosyl](n) + n AMP + 2n H+ + n phosphate.

trimethyllysine dioxygenase activity

Catalysis of the reaction: 2-oxoglutarate + N(6),N(6),N(6)-trimethyl-L-lysine + O2 = 3-hydroxy-N(6),N(6),N(6)-trimethyl-L-lysine + CO2 + succinate.

obsolete N,N'-diacetylchitobiose synthase activity

OBSOLETE. Catalysis of the reaction: n H2O + chitin = N,N'-diacetylchitobiose.

phosphoglucan, water dikinase activity

Catalysis of the reaction: [(1->4)-6-phospho-alpha-D-glucosyl](n) + n ATP + n H2O = [(1->4)-3,6-bisphospho-alpha-alpha-glucosyl](n) + n AMP + 2n H+ + n phosphate.
