'''''S''-메틸시스테인'''({{llang|en|''S''-methylcysteine}})은 [[화학식]]이 CH<sub>3</sub>SCH<sub>2</sub>CH(NH<sub>2</sub>)CO<sub>2</sub>H인 [[아미노산]]이다. ''S''-메틸시스테인은 [[시스테인]]의 ''S''-메틸화 유도체이다. 이 아미노산은 많은 식용 채소를 포함한 식물에서 널리 생성된다.<ref>{{저널 인용|doi=10.1080/01961778208082422|title=Biochemistry of S-Methyl-L-Cysteine and its Principal Derivatives|journal=Sulfur Reports|volume=2|pages=1–26|year=1982|last1=Maw|first1=George A.}}</ref>

== 생합성 ==
S-메틸시스테인은 유전적으로 암호화되어 있지 않지만 시스테인의 [[번역 후 변형|번역 후]] [[메틸화]]에 의해 생성된다. 한 가지 경로는 아연-시스테인산염 함유 복구 효소에 의해 알킬화된 DNA로부터 [[탈메틸화|메틸기 전이]]를 포함한다.<ref>{{저널 인용|doi=10.1111/j.1365-313X.2005.02413.x|pmid=15941393|title=Analysis of Sulfur and Selenium Assimilation in Astragalus plants with Varying Capacities to Accumulate Selenium|journal=The Plant Journal|volume=42|pages=785–797|year=2005|last1=Sors|first1=Thomas G.|last2=Ellis|first2=Danielle R.|last3=Na|first3=Gun Nam|last4=Lahner|first4=Brett|last5=Lee|first5=Sangman|last6=Leustek|first6=Thomas|last7=Pickering|first7=Ingrid J.|last8=Salt|first8=David E.|issue=6|doi-access=free}}</ref><ref>{{저널 인용|doi=10.1074/jbc.AW118.003235|pmid=29743234|title= The ribosome: A Hot Spot for the Identification of New Types of Protein Methyltransferases|journal=Journal of Biological Chemistry|volume=293|pages=10438–10446|year=2018|last1=Clarke|first1=Steven G.|issue=27|pmc=6036201|doi-access=free}}</ref>
