Matrix metalloproteinase-2 is known to be involved in pathological processes such as tumor invasion or rheumatoid arthritis. A soil microorganism producing siderophore under low iron stress $(up\;to\;5\;{\mu}m\;of\;iron)$ was identified as Burkholderia sp. Hydroxamate type siderophore produced by Burkholderia sp. CAS-5 was partially purified. MMP inhibitory activity of siderophore was confirmed by gelatin zymography. The $Zn^{2+}-chelating$ activity of siderophore correlated with the inhibition of MMP-2 activity.
