@jayneway agreeing with my colleague @AmeliesUncle for an excellent reply to the question as articulated, I would juts like to add :
(a) Recaptured depreciation is the same as allowable "accumulated depreciation" , whether recognized or not
(b) It raises the computed gain by lowering your basis for purposes of gain/loss computation
(c) any gain caused by the accumulated depreciation is "recaptured" and treated as ordinary gain ( not capital gain).
(d) It is a "recapture" in the sense that the allowable depreciation had reduced ( under the Passive Activity Loss Limitation) your ordinary income ( in the past ) and if not, has been accumulated into your suspended losses -- thus lowering your gain from disposition of the asset.
The answers here are general and as @AmeliesUncle pointed out , the interpretation etc. depends on the exact facts and circumstances.
Hope this helps
