spermine/spermidine pathway byproduct is MTA, not SAM[edit]

The image depicting the pathway for biosynthesis of spermine and spermidine from putrescine has 2 mistakes in the form of SAM being listed as a byproduct of the reaction rather than MTA (5'-methylthioadenosine). Minor remarks to add are that the protein names are somewhat blurry and difficult to read with the abbreviations and lack of spacing. 128.249.1.194 (talk) 19:43, 3 November 2011 (UTC)[reply]
