Fig. 4From: Characterization of two Lactococcus lactis zinc membrane proteins, Llmg_0524 and Llmg_0526, and role of Llmg_0524 in cell wall integrityPresence of a cysteine-zinc module in proteins. The cysteine-zinc bond was characterized by PMPS-PAR assays with 20 μM of proteins. MalE-0524Nter (left) or MalE-0526Nter (right) were purified from cultures (ctl; grey squares) and from those that were supplemented with zinc salt (black circles) Values, plus standard deviations, are the means of three independent experimentsBack to article page
