Any process that generates hypoxanthine, 6-hydroxy purine, from derivatives of it without de novo synthesis.

Catalysis of the reactions: liquiritigenin + O2 + [reduced NADPH--hemoprotein reductase] = 2,4',7-trihydroxyisoflavanone + H2O + [oxidized NADPH--hemoprotein reductase] and (2S)-naringenin + O2 + [reduced NADPH--hemoprotein reductase] = 2,4',5,7-tetrahydroxyisoflavanone + H2O + [oxidized NADPH--hemoprotein reductase].

Catalysis of the reactions: a flavanone + NADPH + H+ + O2 = a 3'-hydroxyflavanone + NADP+ + H2O, and a 3'-hydroxyflavanone + NADPH + H+ + O2 = a 3',5'-dihydroxyflavanone + NADP+ + H2O.

Catalysis of the reaction: H(+) + liquiritigenin + NADPH + O(2) = H(2)O + licodione + NADP(+).

A region in the lower half of some cells formed from extensive infoldings of the basal plasma membrane; includes cytoplasm adjacent to the infolded membrane.

Catalysis of the reaction: an isoflavone + O2 + reduced [NADPH-hemoprotein reductase] = a 2'-hydroxyisoflavone + H+ + H2O + oxidized [NADPH-hemoprotein reductase].

Catalysis of the reaction: H(+) + NADPH + O(2) + phenylacetone = benzyl acetate + H(2)O + NADP(+).

The oxidation of peptidyl-L-methionine to peptidyl-L-methionine sulfone.

The formation of a protein-protein cross-link between peptidyl-threonine and peptidyl-cysteine by the synthesis of (2S,3S,6R)-3-methyl-lanthionine (3-methyl-L-lanthionine).

The formation of a protein-protein cross-link between peptidyl-serine and peptidyl-cysteine by the synthesis of sn-(2S,6R)-lanthionine (meso-lanthione).

The synthesis of (2R,6R)-lanthionine, sn-(2S,6R)-lanthionine or (2S,3S,6R)-3-methyl-lanthionine, forming an intra-polypeptide cross-link between peptidyl-cysteine, and peptidyl-serine or peptidyl-threonine; dehydration of the serine or threonine residue to the alpha,beta-unsaturated amino acid is the first step; a bond then forms between the ethylene (ethene) group thus formed and the sulfur atom of a cysteine, with the inversion of the configuration of the alpha carbon of the serine or threonine occurring during the process.

The formation of a protein-protein cross-link between peptidyl-serine and peptidyl-cysteine by the synthesis of (2R,6R)-lanthionine (L-lanthionine).
