Catalysis of the reaction: L-serine + pyruvate = 3-hydroxypyruvate + L-alanine.

A protein complex containing flavin adenine dinucleotide (FAD) and acyl-CoA dehydrogenase, which form a system that oxidizes an acyl-CoA molecule and reduces ubiquinone and other acceptors in the mitochondrial electron transport system.

A complex of multiple copies of three enzymatic components: oxoglutarate dehydrogenase (lipoamide) ; EC:1.2.4.2 (E1), dihydrolipoamide S-succinyltransferase ; EC:2.3.1.61 (E2) and dihydrolipoamide dehydrogenase ; EC:1.8.1.4 (E3); catalyzes the overall conversion of 2-oxoglutarate to succinyl-CoA and carbon dioxide (CO2).

pyruvate dehydrogenase (lipoamide) phosphatase complex

A complex of a regulatory and catalytic subunit that catalyzes the dephosphorylation and concomitant reactivation of the alpha subunit of the E1 component of the pyruvate dehydrogenase complex.

Catalysis of the reaction: shikimate + NADP+ = 5-dehydroshikimate + NADPH + H+.

Complex that carries out the oxidative decarboxylation of pyruvate to form acetyl-CoA; comprises subunits possessing three catalytic activities: pyruvate dehydrogenase (E1), dihydrolipoamide S-acetyltransferase (E2), and dihydrolipoamide dehydrogenase (E3).

The series of events by which a mechanical stimulus is received and converted into a molecular signal.

Catalysis of the reaction: ATP + shikimate = ADP + shikimate 3-phosphate.

spermidine catabolism to deoxyhypusine, using deoxyhypusine synthase

The breakdown of spermidine to form deoxyhypusine by the enzyme [eIF-5A]-deoxyhypusine synthase. The reaction occurs in four steps: 1. spermidine + NAD+ = dehydrospermidine + NADH + H+; 2. dehydrospermidine + [enzyme]-lysine = 1,3-diaminopropane + [enzyme]-lysine-N6=CH(CH2)3NH2; 3. [enzyme]-lysine-N6=CH(CH2)3NH2 = [eIF-5A]-lysine-N6=CH(CH2)3NH2; 4. [eIF-5A]-lysine-N6=CH(CH2)3NH2 + NADH + H+ = [eIF-5A]-deoxyhypusine + NAD+.

Catalysis of the reaction: S-adenosylmethioninamine + putrescine = 5'-methylthioadenosine + spermidine.

Catalysis of the reaction: sphingomyelin + H2O = N-acylsphingosine + choline phosphate.
