Protein Function Involved in Spermidine Reduction of Transglutaminase Type 2-Catalyzed β H-Crystallins Polymerization in Calcium-Induced Experimental Cataract
Biochemical Properties The catabolism of spermine to spermidine utilizes either the one-step enzymatic reaction of spermine oxidase (SMO) or the two-step process of spermidine/spermine N (1)-acetyltransferase (SSAT) coupled with the peroxisomal enzyme N (1)-acetylpolyamine oxidase.
PTMs Acetylation
Site(s) of PTM(s)

N-glycosylation, O-glycosylation,
Predicted Disorder Regions NA
DisProt Annotation
TM Helix Prediction No TM helices
Significance of PTMs The acetylated polyamines have two potential fates. First, acetylated polyamines can be exported from the cell. Second, acetylated spermidine and spermine are substrates for the FADdependent, peroxisomal APAO (
Additional Comments  The increase of endogenous SPD in the cultured rabbit lens showed the activation of a flavin adenine dinucleotide (FAD)-dependent polyamine oxidases
