Protein Domain : Syd superfamily IPR038228

Type	Homologous_superfamily
Description	This superfamily contains the Syd protein that has been implicated in the Sec-dependent transport of polypeptides across the inner membrane in bacteria. Syd has been shown to bind the SecY subunit of membrane-embedded SecYEG heterotrimer (also known as core translocon or SecY complex), which is a conserved protein-conducting channel essential for the biogenesis of most of the secretory and integral membrane proteins []. The SecY-binding site of Syd is a conserved concave and electronegative groove that forms interactions with the electropositive loops of the SecY subunit []. Syd is also known to verify the proper assembly of the SecY complex in the membrane by interfering with protein translocation only when the channel displays abnormal SecY-SecE associations [].
