Impact of elevated hydrostatic pressure (45 versus 0.1 MPa) and salinity (11 versus 4% total salts) at 30°C on proteins of H. hydrothermalis

Protein fraction	Protein		Effect of stressora			Comment
	Band label	Approximate mass (kDa)	P	S	P and S
Cytosolic (see Fig. 5A)	l	190	+			S cancels P enhancement
	m	100	+			S cancels P enhancement
	n	90	+			S cancels P enhancement
	o	70	+			S cancels P enhancement
	p	65	+			S cancels P enhancement
	q	60	+	−		S and P cancel each other
	r	50			−	Repression by combination of S and P
	s	43			−	Repression by combination of S and P
	t	40			−	Repression by combination of S and P
	u	35	+	+		S and P combined cancel protein induction by either stress alone

^aThe symbols indicate the relative degrees of change in the intensities of protein bands; a lack of a symbol indicates no significant change. P, pressure; S, salinity.

^bSIP, salt-induced protein.
